Use raw process name for UNIX abstract socket name

Previously we formatted the process name using underscores due to
primitive tooling that has since been replaced.  We can now use the real
process name which fixes an issue with ./scripts/dumpapp output when
there are multiple targets that include derivative processes
(com.mypackage:myprocess).  Previously this would show up as
com.mypackage.myprocess.
