+++ This bug was initially created as a clone of Bug #2181472 +++

Description of problem:

Removing a program from trust database, then reloading fapolicyd, has no effect. The program can still execute, until fapolicyd is restarted, as shown in the example below:

Sample program:
-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------
[user@vm-fapolicy8 ~]$ cat > hello.c << EOF
#include <stdio.h>
int main(int argc, char *argv[])
{
  printf("Hello!\n");
  return 0;
}
EOF

[user@vm-fapolicy8 ~]$ gcc -o hello hello.c
-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------

Program initially untrusted:
-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------
[user@vm-fapolicy8 ~]$ ./hello
-bash: ./hello: Operation not permitted
-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------

Trusting the program:
-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------
[root@vm-fapolicy8 ~]# fapolicyd-cli -f add /home/user/hello
[root@vm-fapolicy8 ~]# fapolicyd-cli -u
Fapolicyd was notified
-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------

Program now trusted:
-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------
[user@vm-fapolicy8 ~]$ ./hello
Hello!
-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------

Untrusting the program:
-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------
[root@vm-fapolicy8 ~]# fapolicyd-cli -f delete /home/user/hello
[root@vm-fapolicy8 ~]# fapolicyd-cli -u
Fapolicyd was notified
-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------

Program untrusted again: (STILL EXECUTES!)
-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------
[user@vm-fapolicy8 ~]$ ./hello
Hello!
-------- 8< ---------------- 8< ---------------- 8< ---------------- 8< --------

Looks like a cache issue.

Version-Release number of selected component (if applicable):

fapolicyd-1.1.3-8.el8_7.1.x86_64

How reproducible:

Always, see above.

I checked with "integrity = sha256", this doesn't help (just in case this was related to BZ #2181544).

This is basically duplicate of BZ #2179701. Different symptoms but the same source. I want to keep both bugzillas open for now.
