yum collapse_libc_requires

[Anders F Björklund]

yum/createrepo has a collapse_glibc_requires option, which only puts the "highest" versioned "libc.so.6" requirement:
    - add option to createrepo config to collapse libc.so.6 requires
    - this will only work with yum 3.2.28 and beyond

This means that the repodata doesn't match the rpm (different dependencies), so smart will view them as separate...
In order to be able to compare packages in Fedora, smart needs to grow a collapse_glibc_requires option as well:
 libc.so.6(GLIBC_2.3.4)(64bit), libc.so.6(GLIBC_2.2.5)(64bit), libc.so.6()(64bit) -> libc.so.6(GLIBC_2.3.4)(64bit)

Note: the real place to fix this, would have been in rpmbuild...

add a test case, as well
