Adds programs.mosh.withUtempter (default: true). The option enables -with-utempter for mosh, allowing it to write to /var/run/utmp and thus making connected sessions appear in the output of `who -a`. For that, a guid-wrapper is required. Also, the path to the `utempter` was hardcoded in the resulting binary until now (so it could never been found), thus, libutempter was patched accordingly to point to /run/wrappers/bin/utempter which at least works when the wrapper is configured.
