tpm2-util: show loaded libraries in 'systemd-analyze has-tpm2'

After 3b16e9f41983f697bc38c40bb8e7119c1bb4f7c8, even the libraries are
documented in the man page, it is useful to mention which libraries are
checked in the command output.

Of course, the dependencies are kind of implementation detail, and may
be changed in the future version, but that's especially why I think
showing the library deps in the output is useful.

systemd-analyze is a debugging tool, and already shows many internal
states. I think there is nothing to prevent from showing the deps.

Prompted by #34477.
