Subject: lint_pkgbuild/variable: increase robustness

Approach the detection of variables of the wrong type using an approach
similar to that used for construction of .SRCINFO files. While doing silly
things in bash could still result in false negatives, this approach should
be very robust to generatinf false positives results.
