pkgtools/pkglint: update to 22.2.3

Changes since 22.2.2:

CHECK_WRKREF is known to pkglint, which prevents conditions using this
variable from being simplified in a wrong way.

For variables that are guaranteed to be defined, suggest to simplify the
condition '!empty(VAR:M[Yy][Ee][Ss])' to '${VAR:M[Yy][Ee][Ss]}', as that
reduces the number of negations in the condition.

Detect redundant WRKSRC definitions and suggest to remove them.

Fix wrong "c99 is not valid for USE_LANGUAGES" warnings.
