[PATCH v4 08/11] qemu: Extend swtpm_setup command line to set a profile by its name

[Stefan Berger <stefanb@xxxxxxxxxxxxx>]

Run swtpm_setup with the --profile-name option if the user provided the
name of a profile. swtpm_setup will try to load the profile from
directories with local profiles and distro profiles and if no profile
by this name with appended '.json' suffix could be found there, it will
fall back to try to use an internal profile with the given name.

Also set the --profile-remove-disabled option if the user provided a value
in the remove_disabled attribute in the profile XML node.
