services: qemu-binfmt: Preserve argv[0] by default.
Previously, argv[0] would be replaced by the absolute file name of the
executable. This could cause discrepancies, for example in the
Coreutils test suite: <https://issues.guix.gnu.org/49485>.
* gnu/services/virtualization.scm (<qemu-platform>)[flags]: Default to "FP".
