meson: don't probe for -Werror if --werror is enabled

Browse Source 
Meson has its own mechanism to turn on -Werror with the --werror option.
If this is set, then there is no reason for libvirt to check for -Werror
itself.

We remove the summary line output because it is potentially misleading
when libvirt hasn't enabled -Werror, but meson has.
