pwd-unreadable-parent: Skip test on non-Linux/GNU systems.

* tests/misc/pwd-unreadable-parent: Rather than trying to decide
whether this test has a chance of succeeding, run it only when
$(host_os) is linux-gnu.  It was failing on powerpc-apple-darwin8.8.0
* tests/misc/Makefile.am (TESTS_ENVIRONMENT): Add host_os=$(host_os).
