Subject: [PATCH] remove libc/sock/if.h

libc/sock/if.h is removed because:

- it contained only IFNAMSIZ, which was also defined in
  libc/sock/struct/ifreq.h
- it was not included in any file EXCEPT libc/isystem/net/if.h, which
  also included the libc/sock/struct/ifreq.h

hence we remove this file, and move the IFNAMSIZ definition to
libc/sock/struct/ifreq.h which is included in isystem.
