sysutils/kio-fuse: fix build on GCC architectures

ENODATA is not defined on GCC systems:
/wrkdirs/usr/ports/sysutils/kio-fuse/work/kio-fuse-4.95.0/kiofusevfs.cpp: In static member function 'static int KIOFuseVFS::kioErrorToFuseError(int)':
/wrkdirs/usr/ports/sysutils/kio-fuse/work/kio-fuse-4.95.0/kiofusevfs.cpp:2323:55: error: 'ENODATA' was not declared in this scope
2323 | case KIO::ERR_NO_CONTENT : return ENODATA;

Guard it behind ifdef.
