Revert "Blacklist tests failing on valgrind."

We use the msync syscall to test if pages are mapped without actually
getting a segv. Valgrind (correctly) sees this as an illegal access.
We need to add the testing function to the valgrind suppression file.

Reason for revert: Added required valgrind suppressions

This reverts commit 45a6da0f.
