lib/common.sh: Adjust to work properly with `set -u`
Support for working with `set -u` was broken by 94160d6. Egg on my face; I'm the one who wants `set -u` support, and I'm the author of that commit! libmakepkg does not work with `set -u`; but mostly because of the include guards! So we just need to temporarily disable `set -u` (nounset) while loading libmakepkg. Instead of introducing a new variable, just store the initial nounset status in _INCLUDE_COMMON_SH; rather than a useless fixed-string "true". While we're at it, disable POSIX-mode (just in case we're running as "sh" instead of "bash"), since libmakepkg uses bash-isms that won't parse in POSIX mode.
