makepkg: Move parseopts from library to libmakepkg

parseopts is used in makepkg and other scripts such as pacman-key as a
getopt replacement.

Instead of including it in those scripts via a macro, move it to
libmakepkg/util/parseopts.sh and have scripts source this file where
appropriate.

To keep the parseopts test, a new variable was introduced:
PM_LIBMAKEPKG_DIR
