services/qemu-binfmt: Use the F flag and the static output of QEMU.
Fixes <https://issues.guix.gnu.org/36117>.

Before this change, the 'binfmt_misc' entries registered for QEMU would not be
usable in container contexts outside of guix-daemon (without manually bind
mounting file names).

For example:

$ docker run --rm arm32v7/debian true
standard_init_linux.go:207: exec user process caused "no such file or directory"

After this change, any container can make use of the QEMU binfmt_misc
registrations, as their corresponding QEMU static binaries are fully
pre-loaded by the kernel.

* gnu/services/virtualization.scm (<qemu-platform>): Define using
'define-record-type*'.
[flags]: New field, which defaults to "F" (fix binary).
