stmhal/moduselect: Expose POLLIN/OUT/ERR/HUP constants.

pfalcon · pfalcon · commit 746b752b8efd · 2015-11-09T22:10:31.000+02:00
This makes select.poll() interface fully compatible with CpYthon. Also, make
their numeric values of these options compatible with Linux (and by extension,
with iBCS2 standard, which jopefully means compatibility with other Unices too).
