I accidentally did a signed comparison of the size_t values passed in
for three of the _chk functions. Changing them to unsigned compares.
Add three new tests to verify this failure is fixed.

Get rid of a lot of the duplication in the various FORTIFY_SOURCE
tests. Instead, we build 4 separate static libraries, with
4 different compile time options, and link them into the final test
binary.
