makepkg: rework libprovides
This reworks the implmentation of libprovides for the following benefits: - Moves functionality from write_pkginfo() to find_libprovides() - Only calculates the version for libraries specifically requested and not all libraries. This has the disadvantage of running find over the $pkgdir for as many libraries as needed, but is unlikely to be an issue due to caching. - The order of the provides array in the PKGBUILD is kept in the package - There are more warning messages when things fail and those that were there are no longer errors (as I do not think failure of libprovides should result in complete packaging failure) - It is now modular so can be easy extended to other library types other than ELF *.so.
