py/modsys: Introduce sys.implementation._machine constant.

This contains a string useful for identifying the underlying machine.  This
string is kept consistent with the second part of the REPL banner via the
new config option MICROPY_BANNER_MACHINE.

This makes os.uname() more or less redundant, as all the information in
os.uname() is now available in the sys module.
