tests: remove stale surrogate-pair test

The cygwin-specific code for surrogate pairs was first disconnected
via v2.21-62-g936c904 and later removed as part of a then-unused
function via v2.24-12-g704de87. So now I'm removing the test, too.
If someone thinks it important and would like to revive it, please do.
* tests/surrogate-pair: Remove file.
* tests/Makefile.am (TESTS): Remove it.
