spicebird Provides pollution

[Michael Schwendt]

Spicebird in rawhide provides 46 sonames, which are provided by
the following other packages:

  nss
  nspr
  mozldap
  xulrunner

It does so for libs stored outside run-time linker's search path. This leads
to weak RPM dependencies. The worst-case scenario would be that one could
remove a required package, because RPM believes that spicebird is one
of multiple packages which satisfy the requirement.

Two examples of how the soname provides are polluted:

nss provides libssl3.so(NSS_3.2)
spicebird provides libssl3.so(NSS_3.2)

And during installation of those packages, it's only the "shortest pkg name
wins" in Yum depsolving, which protects us from problems. Plus explicit deps
on specific pkg names.
