test: tpm: pass optional machine options to swtpm test functions

We plan to use swtpm test functions on ARM for testing the
sysbus TPM-TIS device. However on ARM there is no default machine
type. So we need to explictly pass some machine options on startup.
Let's allow this by adding a new parameter to both swtpm test
functions and update all call sites.
