Fix basename usage in pacman and utilities
basename() is a rather untrusty function call on a lot of platforms as it does some weird and different things. To solve this, I added a mbasename fuction to pacman to take its place, and simply removed its usage in the utilities (it isn't worth dealing with there). Signed-off-by: Dan McGee <dan@archlinux.org>
