main: Check bitbake server-only port is a number

Either using the memres script or the bitbake call with --server-only
if the port is a string instead of a number then the process hangs
indefinitely causing a loop that never ends.

Add a check at the beginning for the port being a number otherwise
show an error message and exit cleanly.
