  lxc-debian: allow to specify a binfmt interpreter

If you specify an interpreter path with "-I" or "--interpreter-path",
the architecture of the debian container can differ from the one of
the host.

Before creating the container, binfmt must be configured on the host:
the script checks the name of the interpreter in /proc/sys/fs/binfmt_misc/
to know where to install it in the container.

To create a MIPS container on an x86_64 host:

$ cat /proc/sys/fs/binfmt_misc/qemu-mips
enabled
interpreter //qemu-mips
flags: OC
offset 0
magic 7f454c4601020100000000000000000000020008
mask ffffffffffffff00fffffffffffffffffffeffff

$ sudo lxc-create -n virtmips-stretch -t debian -- \
           --arch=mips \
           --interpreter-path=./mips-linux-user/qemu-mips \
           --mirror=http://ftp.debian.org/debian \
           --release=stretch
