virtiofsd requires libcap-ng:

    ../tools/meson.build:12:6: ERROR: Problem encountered: virtiofsd requires libcap-ng-devel and seccomp-devel

Run `autogen.sh` in the source directory, as it requires `configure.ac`
in the same directory, and Bee’s buildtype *autogen* is run from the
build directory. Running it manually, the buildtype *autotools* is used.

    [BEE] using magic buildtype 'autotools' from '/usr/libexec/bee/beesh.d/autotools.sh' ..
