Subject: [PATCH] errno-util: rework ERRNO_IS_RESOURCE() from macro into static
 inline function

No technical reason, except that later on we want to add a new
ERRNO_IS() which uses the parameter twice and where we want to avoid
double evaluation, and where we'd like to keep things in the same style.
