qemuxml2argvtest: Fix type for faked chardev backing a TPM
qemuxml2argvtest: Fix type for faked chardev backing a TPM

The test filled the chardev type to VIR_DOMAIN_CHR_TYPE_FILE and thus
set the 'data.emulator.source->data.file.path' pointer, but the
commandline formatter is unconditionally expecting VIR_DOMAIN_CHR_TYPE_UNIX
and thus reading 'data.emulator.source->data.nix.path'. Since it's an
union it happened to land in the correct place. Fix the faked data.
