qemu-binfmt-conf.sh: mips: allow nonzero EI_ABIVERSION, distinguish o32 and n32

With the command line flag -mplt and a recent toolchain, ELF binaries
generated by gcc can obtain EI_ABIVERSION=1, which makes, e.g., gcc
three-stage bootstrap in a mips-unknown-linux-gnu qemu-user chroot
fail since the binfmt-misc magic does not match anymore. Also other
values are technically possible. qemu executes these binaries just
fine, so relax the mask for the EI_ABIVERSION byte at offset 0x08.

In addition, extend magic string to distinguish mips o32 and n32 ABI.
This information is given by the EF_MIPS_ABI2 (0x20) bit in the
e_flags field of the ELF header (a 4-byte value at offset 0x24 for
the here applicable ELFCLASS32).

linux-user: manage binfmt-misc preserve-arg[0] flag

Add --preserve-argv0 in qemu-binfmt-conf.sh to configure the preserve-argv0
flag.

This patch allows to use new flag in AT_FLAGS to detect if
preserve-argv0 is configured for this interpreter:
argv[0] (the full pathname provided by binfmt-misc) is removed and
replaced by argv[1] (the original argv[0] provided by binfmt-misc when
'P'/preserve-arg[0] is set)

For instance with this patch and kernel support for AT_FLAGS:

$ sudo chroot m68k-chroot sh -c 'echo $0'
sh

without this patch:

$ sudo chroot m68k-chroot sh -c 'echo $0'
/usr/bin/sh

The new flag is available in kernel (v5.12) since:
2347961b11d4 ("binfmt_misc: pass binfmt_misc flags to the interpreter")

This can be tested with something like:

# cp ..../qemu-ppc /chroot/powerpc/jessie

# qemu-binfmt-conf.sh --qemu-path / --systemd ppc --credential yes \
--persistent no --preserve-argv0 yes
# systemctl restart systemd-binfmt.service
# cat /proc/sys/fs/binfmt_misc/qemu-ppc
