build: add libintl dependency to meson and the .pc file

In order to use gettext on systems where it is not part of libc, the
correct linker flags are needed in libalpm.pc (for static compilation).
This has never been the case.

The new meson build system currently only checks for ngettext in libc,
but does not fall back to searching for the existence of -lintl; add it
to the libalpm dependencies.
