security: Add DAC and SELinux security for tpm-emulator

Browse Source 
Extend the DAC and SELinux modules with support for the tpm-emulator.
We label the Unix socket that QEMU connects to after starting swtmp
with DAC and SELinux labels. We do not have to restore the labels in
this case since the tpm-emulator will remove the Unix socket when it
terminates.
