Subject: libmakepkg: check if PKGBUILD variables are arrays or not as
 appropriate

When extracting variables from PKGBUILD (e.g. for .SRCINFO creation) we make
assumptions about whether variables are arrays or not.  This adds a check to
the PKGBUILD linter to ensure variables are arrays or not as appropriate.
