Change to provides for kernel-PAE-modules-extra

[Bruno Wolff III]

kernel-PAE-modules-extra used to provide kernel-modules-extra. This allowed 
packages that needed either to just require kernel-modules-extra. I see 
that both provide installonlypkg(kernel-module). Should packages that 
need either require that instead?

This affects at least the following packages (maybe indirectly):
gfs2-utils
joystick-support
libguestfs
perl-Sys-Guestfs
python-libguestfs
virt-v2v
