spa: support: logger: print thread id for each message

Browse source 
The thread id is very useful for debugging, add it to the every log
message so that it does not have to be inferred from the content itself.

This is already done in the systemd journal logger, so implement
it here as well.

Before:

  [I][00:13:11.120303] pw.context   | [      pipewire.c:  585 pw_init()] version 1.7.0

After:

  [I][365073][00:13:11.120303] pw.context   | [      pipewire.c:  585 pw_init()] version 1.7.0
