virtme-ng: introduce -q/--quiet

[arighi]

Introduce an option to nullify the effect -v/--verbose.

This option can be useful to override certain wrappers / aliases around vng, as pointed out in issue #58.

this looks right, but for some reason I cant install it to test.

[jimc@frodo virtme-ng]$ make
cd virtme_ng_init && cargo install --path . --root ../virtme/guest

warning: be sure to add ../virtme/guest/bin to your PATH to be able to run the installed binaries

that last line is not right: ../guest/bin doesnt exist, anywhere under HOME,
more particularly, none of:

[jimc@frodo projects]$ ll -d virtme*

, has a guest/bin under it

the closest I can find is:

virtme-ng-init is installed in ./virtme/guest/bin inside the virtme-ng source dir. Also I never use make, it's there just to build virtme-ng-init. To build the whole virtme-ng I usually do BUILD_VIRTME_NG_INIT=1 pip install --break-system-packages .. This will install everything under your $HOME/.local so it can be done as regular user and it will override the system virtme-ng. Maybe I can add a make install target that does this...

Thanks!
vng -bv -q # works, is silent as expected.
