correctly label pulpcore-(api|content) binaries

[evgeni]

since pulpcore 3.33 there are new binaries to start pulpcore services, but those binaries were not properly labeled with pulpcore_server_exec_t like their old counterpart gunicorn
without that label, the services run as unconfined_service_t, which results in errors like httpd not being able to connect to them

while at it, also properly label the pulpcore-worker binary in /usr/bin

The denial I am seeing is btw:

note that tcontext is unconfined_service_t which is wrong :)

Looking at theforeman/puppet-pulpcore@7e12c0f#diff-36f3fbc255f9dd485363f6d80f241bfbfc87d30b7e11e285f7e620cbcb6f6425 (both templates) it previously used /usr/libexec/pulpcore/gunicorn so this is correct.
