emulators/wine-devel: Unconditionally set MAINTAINER and COMMENT

The MAINTAINER and COMMENT variables, as well as PKGNAMESUFFIX and
WINELIBDIR, could be overridden for the sake of the i386-wine-devel
port. With that port gone, simply set these unconditionally.

This is mostly 6387592 forward
ported from emulators/wine.
