ipc/chromium: fix #if define() for kFreeBSD and Hurd

The kFreeBSD and Hurd platforms need some other macros to include
the correct needed headers.
Depended on this some minor changes to call the correct functions
also needed. Also the list of the cpp source file for the chromium
things needs to expanded.
The changes is an adoption of the previous dropped patch 'Fix
ipc/chromium on kFreeBSD and Hurd' from the version 17.
