  [PlayStation][Debug] Build fix after 268047 at main
https://bugs.webkit.org/show_bug.cgi?id=261725

Reviewed by Chris Dumez.

268047 at main added HAVE_SCHEDULING_POLICIES, which is a condition to manage
a scheduling policy but schedPolicy() is defined with no condition.
It is detected as an unsed warning and causes a build error due to
"-Werror,-Wunused-function" in build configurations where it is debug build
and schedPoilicy() is not used.  To fix the break, schedPolicy() needs to be
defined with HAVE(SCHEDULING_POLICIES) and OS(LINUX),

* Source/WTF/wtf/posix/ThreadingPOSIX.cpp: Added a condtional macro for SCHEDULING_POLICIES and OS(LINUX) to schedPolicy().
