Remove mentions of CLONE_PID and CLONE_STOPPED

CLONE_PID was removed in Linux 2.5.15 and recycled for
CLONE_PIDFD since Linux 5.2.
CLONE_STOPPED was removed in Linux 2.6.38 and recycled
for CLONE_NEWCGROUP since Linux 4.6.

sched.h: Linux documents clone and __clone as only available
when_GNU_SOURCE is defined - follow suit.
Ok martin@

clone(2): document that _GNU_SOURCE must be defined for the prototypes
sched.h: format comment to follow KNF
requested by thorpej@
sched.h: keep __clone() visible under _NETBSD_SOURCE
