imkmsg fix: Handle EAGAIN/EWOULDBLOCK check portably
On some systems, EAGAIN and EWOULDBLOCK are defined to the same
value, causing a `-Wlogical-op` warning for the redundant logical
'or' in the errno check.

While portable code must check for both cases, this warning is
unwanted.

This change uses a preprocessor directive to conditionally compile
the check for `errno == EWOULDBLOCK` only on platforms where its value
differs from EAGAIN. This silences the warning without affecting
portability.
