[trace] Look harder for the cairo-trace.so library.

On OpenBSD the convention is to not use symlinks from
unversioned library names to versioned library names.
This breaks cairo-trace because it looks for cairo-trace.so
explicitly, but on OpenBSD only cairo-trace.so.0.0 is
installed.

The right thing to do is probably to source the cairo-trace.la
file and look for a file name there somehow.  Instead this commit
just looks for a likely looking file or symlink in the install
directory.
