win: remap ERROR_NOACCESS and ERROR_BUFFER_OVERFLOW (#4567)

Browse Source 
It seemed incorrect to map a segfault to EACCES, since posix would typically
map this to EFAULT. The ERROR_BUFFER_OVERFLOW is literally "the filename is too
long", and is not typically an invalid parameter in posix.

Test originally added in #1060 to test the API, not the value.
