checkpatch.conf: Update rules

- Remove the "MISSING_SPACE" check which checks for breaks at a space in
a string concatenation.  Most of the time this makes sense, but we
occasionally need to break where there isn't a space, so having a hard
rule doesn't always work.

- Don't check the vendorcode directory for compliance to coreboot's
code format rules.
