abump: source APKBUILD in subshell

As demonstrated in b7813c3 (abump: demonstrate abump environment
polution, 2022-10-15), sourcing APKBUILDs in abump polutes it's
environment.

Address that by sourcing the APKBUILD in a subshell as well as some of
the checks following it that need the information from the APKBUILD.
That information is not used any later, it's not an issue that it's
discarded outside of the subshell.
