Stefan Berger b255d07010 tests: Move swtpm_open_cmddev into swtpm_cmd_tx
Move swtpm_open_cmddev call into swtpm_cmd_tx since the latter function is
always called in a subshell that previously inherited the file descriptor
opened by the test cases. Remove swtpm_cmd_tx from nearly all test cases
and also remove closing of file descriptor 100 via 'exec 100>&-' from test
cases since this is not necessary anymore.
