Skip standard compilers check for unknown Xcode

Rescuing false on the StandardCompilers map meant that the doctor
check assumed that the compilers were incorrect, not merely

Instead, skip the check and return nil for unknown Xcode; nil
should be interpreted as "dunno", instead of "true" or "false",
and the doctor check no longer prints on nil.
