  linux-user: disable qemu-bridge-helper and socket_scm_helper build

linux-user targets don't need them, and if we ask to build statically
linked binaries, some static libraries they need are not available.

  qemu-binfmt-conf.sh: ignore the OS/ABI field

Most of the binaries have a value of "UNIX - System V" for the OS/ABI.

But cc1 has a value of "UNIX - GNU", and if we don't update the binfmt
mask to ignore the OS/ABI field, gcc fails to execute it:

gcc: error trying to exec '/usr/lib/gcc/m68k-linux-gnu/7/cc1': execv: Exec 
format error
