meta-phosphor: phosphor-defaults: clean up poor line continuations

The phosphor-defaults.inc file has some free-standing line continuations
that aren't in strings.  While this might be accepted by bitbake, I
don't think it is intended to be valid syntax, and the upstream
vimsyntax file isn't happy about it.  Clean this up by removing the
continuation.
