ortp: Fix the version check for ORTP by not using the cached result
The second check used the cached result for ORTP. Store the result
in ORTP_VERSION and my system properly detects that it is running
on < 0.21.
The HAVE_ORTP_021 will always be defined so just use #if and not
the #ifdef to fix the build.
