Install the swtpm package, if available

The "boot_aggregate.test" requires either a hardware or software TPM.
Support using the swtpm, if packaged for the distro, in addition to
tpm_server.

Note: Some travis/<distro>.sh scripts are links to other scripts.
Don't fail the build of the linked script if the swtpm package doesn't
exist.
