[examples] Skip building the Bye pass plugin on windows

Browse Source 
Windows doesn't properly support pass plugins (as a shared library
can't have undefined references, which pass plugins assume, being
loaded into a host process that contains provides them), thus
disable building it and the corresponding test.

This matches what was done for the passes unit test in
bc8e44218810c0db6328b9809c959ceb7d43e3f5.
