tools/mpremote: Refactor error handling to apply generally to any errno.

This rewrites the code that previously manually emitted and caught various
OSError subclasses with equivalent code that uses the errno name dictionary
to do this generically, and updates the exception handler in do_filesystem
to catch them in a similarly-generic fashion using os.strerror to retrieve
an appropriate error message text equivalent to the current messages.

Note that in the CPython environments where mpremote runs, the call to the
OSError constructor already returns an instance of the corresponding mapped
exception subtype.
