Subject: [PATCH 1111/1160] missing_sched: add CLONE_PIDFD

CLONE_PIDFD was introduced in v5.2 and in sched.h in glibc-2.31 so
without this, building with older version fails with:

src/basic/raw-clone.h:41:108: error: 'CLONE_PIDFD' undeclared (first use in this function); did you mean 'CLONE_FILES'?

(cherry picked from commit e91c5cf06ab7ca9e5576c6feac5f743927f2b063)
(cherry picked from commit 480e39dbbb3df253e02a4908dfcfecf1fb3511e2)
(cherry picked from commit 5e0588e3d97715da9995013eb8dbc13eb21a8d0b)
