When testing clang that has been compiled with `-DDEFAULT_SYSROOT` set to some
path,
the test `VFSGCCInstallation` would fail, because the search always starts
either
in the default sysroot (which doesn't exist in the just-created in-memory VFS),
or in
`${CLANG_BINARY_DIR}/../lib`, while the virtual GCC installation is in
`${CLANG_BINARY_DIR}/../usr/lib`.
Override sysroot to be empty string for the test to succeed.
(Note that a very similar test `VFSGCCInstallationRelativeDir` was passing
because
the GCC installation was, in fact, in `${CLANG_BINARY_DIR}/../lib`.)
