glibpacrunner: fix crash on error

glibpacrunner was asserting that g_proxy_resolver_lookup() didn't
return an error (since libproxy 0.3 always returned a non-error
response no matter what happened). But libproxy 0.4 does error out and
return NULL in some rare cases, so we need to allow for that.

fix previous commit
tls: fix installed tests

The support files weren't being installed, but rather were still being
read out of the source tree. Fix that.

tls: fix installed tests differently

The previous patch worked for "make check" and for running the
installed tests, but failed when running tests by hand, because
G_TEST_SRCDIR wouldn't be set, so it would just use "./", and then
GFileDatabase would complain that you had passed it a relative path.

Re-fix by adding a helper method to force-absolutify the paths, if
needed. (Also, intern the path names to avoid needed all the g_free()s
from the previous patch.)
