makepkg: rework libdepends

Rewrite the handling of libdepends. The primary advantage are:
 - Moves functionality from write_pkginfo() to find_libdepends().
 - The order of the depends array in the PKGBUILD is kept in the package.
 - An unneeded libdepends is only a warning and not an error. This allows
   putting a libdepend on a library that is dlopened.
 - It is now modular so can be extended to library types other than
   ELF *.so.
 - Finding the list of libraries a package depends only occurs when a
   libdepend is specified in the depends array.
