snap: Update for QEMU 5.2.0

QEMU 5.2.0 needs ninja-build package installed on the build environment.

The default-configs were copied to $QEMU_SRC/default-configs but that does
take any effect, so instead it is now copied to $QEMU_SRC/default-configs/devices
and the configs for i386 were updated.

Also it had to change some arguments being passed to configure as Meson was failing
due inconsistent paths:

  ./meson.build:1:0: ERROR: The value of the 'libdir' option is '/usr/lib/qemu' which must be a subdir of the prefix '/snap/kata-containers/current/usr'.
  Note that if you pass a relative path, it is assumed to be a subdir of prefix.
