[Buildroot] [git commit branch/next] package/qemu: add option to install blobs

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=97c40266b1b69e101ce035c8aa73bf2665c5c256
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/next

Binary blobs are BIOS of some sorts for the various machines emulated
by QEMU. There is no option to individually install blobs; it's an
all-or-nothing option.
