[Buildroot] [PATCH v2 3/3] qemu: disable qemu user emulation on MIPS64 for host variant

From: Adam Duskett <Adamduskett at outlook.com>
According to target/mips/TODO in the Qemu sources:
===
MIPS64
------
- Userland emulation (both n32 and n64) not functional.
===
And indeed, trying to run a mips64n32 binary under qemu user emulation
results in:
Invalid ELF image for this architecture
So we move the BR2_mips64(el) dependency from
BR2_PACKAGE_HOST_QEMU_ARCH_SUPPORTS to
BR2_PACKAGE_HOST_QEMU_SYSTEM_ARCH_SUPPORTS, so that only the system
emulation is available on mips64, and not the user-mode emulation.
