gh-149879: Fix test_strptime on Cygwin

[vstinner]

Skip my_MM and or_IN locales on multiple tests, since the tests fail on Cygwin.

• Issue: Enhance Cygwin support #149879

[vstinner]

Cygwin uses the newlib C library. Multiple test_strptime tests with my_MM and or_IN locales.

Oh, I would have liked a solution that covers some more platforms, since I know Solaris has similar issues with its system libraries.

[vstinner]

The skip_cygwin_locale() function can be renamed to skip_broken_locale() and adapted to skip other locales on other platforms.
