Update rm2fb to v0.0.4

This update includes a change in the server code to set the server
process name to 'rm2fb-server' (instead of the default 'xochitl'). See
also #359 and rmkit-dev/rmkit#127.

Test plan: Started the 'rm2fb' service, retrieved the server PID, and
made sure that both `/proc/PID/cmdline` and `/proc/PID/stat` contained
'rm2fb-server' instead of 'xochitl'.
