ssize is a POSIX.1-2001 extension, which may or may
not be provided by the C library, or may be defined
to a different size in the host and embedded C library.
Two internal functions were returning ssize, but
one of them was a trampoline into the same host API,
which is already provided by the native simulator
so let's just use that instead.
The other is only carrying data that fits into an
int and is anyhow being cast in/to ints, so let's just
avoid the trouble by defining it as returning int.

Rename the native Linux SocketCAN driver to reflect that it can can now be
used in both native_posix and native_sim (with or without an embedded
C-library).
