rG1a8d176432e7: inpcb: fully retire inp_ppcb pointer

Summary

Before a protocol specific control block started to embed inpcb in self
(see 0aa120d52f3c, e68b3792440c, 483fe96511ec) this pointer used to point
at it.

Retain kf_sock_inpcb field in the struct kinfo_file in <sys/user.h>. The
exp-run detected a minimal use of the field in ports:

sysutils/lsof - patched
net-mgmt/etdata - patch submitted upstream
emulators/qemu-user-static - upstream master branch seems not using the field anymore

We can keep the field around for some time, but eventually it may be reused
for something else.

PR: 277659 (exp-run)
