librestage: clean up, add unit tests

Contained the text "# TODO refactor this", and I can't just stick to that
fragment of code, can I?

I actually didn't change too much, despite what the diff looks like.
 - move everything into a main() routine
 - redo the usage() text
 - rename a few variables
 - fix where "${#repos}" should have been "${#repos[@]}"
 - use [[...]] instead of [...]
 - use "if A; then B; else C; fi" instead of "A || C && B"
 - use CARCH instead of looping over every possible architecture.
 - only look for files that match PKGEXT, as set in makepkg.conf
 - pull out duplicate code for error handling
 - don't warn when creating "staging/REPONAME"
