common/attr: fix check for _require_attrs()

As of now xfstests decides if a filesystem supports attributes by trying
to write one to the mount point. For some reason this fails on reiserfs,
making it impossible to run tests that _require_attrs.

Fix this by checking against $TEST_DIR/syscalltest instead of $TEST_DIR.

This is probably what was intended, since the syscalltest file is touched
right before running attr. It is also consistent with how the check for
acl support is done.
