tracing/remotes: Add trace_remote cmdline options

This commit adds the trace_remote= kernel command-line option to configure
trace remote options and enable events upon registration.

[Severity: Low]
This isn't a bug, but per the cleanup.h convention, __free() variables
should be defined and initialized in a single statement after the
!trace_remote_cmdline[0] check rather than declared as = NULL at the top
of the function and assigned later.
