Description of problem:

When upgrading packages on a production server, we find it desirable to "nice"
the update process.  Unfortunately, this interacts poorly with the post-install
restart logic and the initscripts daemon logic.  The attached patch changes
initscripts to treat NICELEVEL and the nicelevel argument to daemon() as
absolute nicelevels, and uses nice to adjust the level accordingly.  It has an
unfortunate dependency on the coreutils /bin/nice SUSv3-compatible extension
which causes nice to return the process nicelevel if a command to execute is
not specified.  

Version-Release number of selected component (if applicable):
initscripts-8.38-1 and earlier.

How reproducible:
Always.

Steps to Reproduce:
1. nice rpm -Uvh openssh*.rpm
2. ps -o command,nice -p $(pgrep -x sshd)
  
Actual results:
COMMAND                      NI
/usr/sbin/sshd               10

Expected results:
COMMAND                      NI
/usr/sbin/sshd                0
