Description of problem:
%update_maven_depmap calls find utility, but does not require findutils. This leads to macro failure if findutils are not installed.

Version-Release number of selected component (if applicable):
1.7.5-20.fc18

How reproducible:
always

Steps to Reproduce:
1. prepare a chroot at /chroot
2. install a package that calls %update_maven_depmap in its scriplet (for example xpp3)
 # yum --installroot /chroot install xpp3
  
Actual results:
  Installing : xpp3-1.1.3.8-7.fc18.noarch
/var/tmp/rpm-tmp.epHhD4: line 3: find: command not found

Possible solutions:
1) add findutils to requires

2) redefine %update_maven_depmap as %nil
This macro is no longer needed and therefore can be replaced with NIL.
