[Buildroot] [PATCH v2] qemu: fix host virtfs option

[Vincent Stehlé]

Fix the build of host-qemu with virtfs enabled: fix a typo in makefile
conditional and add a dependency on host-libcap.

The virtfs configuration option was added by commit e0f49e648401
("package/qemu: add option to enable virtual filesystem in host qemu").

Changes v1 -> v2:
  - Forcibly disable virtfs when config option is =n rather than letting
    qemu auto-detect (as per Thomas' feedback)
