samples: create lock with name .lock.swtpm-localca rather than .lock

To avoid clashes with the lock files created by swtpm, have
swtpm-localca creata a lock file with the name .lock.swtpm-localca
so they can share directories if necessary.

This patch makes tests/test_tpm2_swtpm_setup_create_cert run on
OpenBSD since the swtpm and swtpm-localca then do not interfere
with the file locks. This doesn't seem to be an issue on Linux
or Cygwin, though, where probably the file locking is implemented
differently.
