[Virtio-fs] [PATCH 1/2] meson: Check for seccomp/cap-ng libraries if virtiofsd is enabled

[Philippe Mathieu-Daudé]

When not explicitly select a sysemu target and building virtiofsd,
the seccomp/cap-ng libraries are not resolved, leading to this error:

  $ configure --target-list=i386-linux-user --disable-tools --enable-virtiofsd
  tools/meson.build:12:6: ERROR: Problem encountered: virtiofsd requires libcap-ng-devel and seccomp-devel

Fix by checking the seccomp/cap-ng libraries if virtiofsd is built.
