rdp: Check for non-numeric value in RDP_FD env var

strtoul(nptr, endptr, ...) will set *endptr to nptr in the case of where
no digits were read from the string, and return 0.  Running with
RDP_FD=foo would thus result in fd=0 being specified to
freerdp_peer_new(), which is unlikely to be the user's intent.
