Tests: Explicitly set permissions in CPack tests to avoid perimssions errors

When the user has the setgid bit is set on the parent directory of
the build directory, the setgid bit will be propagated throughout the
build tree.  Most tests do not care about permissions as long as they
can read and write the files the need.  The CPack tests, however, validate
that permissions match an expected set, and fail with the setgid bit set.

Explicitly set permissions on directories created in the CPackTestHelpers
to clear the setgid bit.
