```
std.os: add missing mmap errors

Man page for posix lists EMFILE, man page for linux ENFILE.
Also posix says "The mmap() function adds an extra reference to the file
associated with the file descriptor fildes which is not removed by a
subsequent close() on that file descriptor. This reference is removed
when there are no more mappings to the file."

It sounds counter-intuitive, that a process limit but no system limit can
be exceeeded.

As far as I understand, fildes is only used for file descriptor backed mmaps.
