While trying to change the number of missing deps output by makepkg, I noticed

some needless complication in a few of these functions (checkdeps required
stderr output due to the way it was called/used) so that's all cleaned up now.
Also, makepkg no longer outputs a single dep when they are missing, it lists all
at once, including makedeps

scripts/makepkg
