build: expand rule to cover testsuite

The bulk of this patch was done with:

sed -i 's/\(\bfree *(/VIR_FREE(/g' tests/*.c

followed by fixing the few compile errors that resulted.

* cfg.mk (exclude_file_name_regexp--sc_prohibit_raw_allocation):
Remove tests from exemption.
* tests/testutils.h: Add common header.
* tests/commandhelper.c: Fix offenders.
* tests/cputest.c: Likewise.
* tests/domainsnapshotxml2xmltest.c: Likewise.
