Change it from lib_t to textrel_shlib_t

This is discussed in the FC5 SELinux FAQ at:
http://fedora.redhat.com/docs/selinux-faq-fc5/
(I have a process running as unconfined_t, and SELinux is still
preventing my application from running)

Unfortunately there is a typo in the FAQ and it tells you to use
testrel_shlib_t instead of textrel_shlib_t.
