Catch EnvironmentError instead of OSError/IOError

menuconfig.py tended to crash on I/O errors on Python 2, due to
forgetting to update some 'except OSError's. Catch EnvironmentError
instead.

EnvironmentError is a common base class of IOError and OSError on Python
2, and an alias for OSError on Python 3. Use it elsewhere too, as it
might help catch obscure I/O errors on Python 2.
