syscall: remove a wrong comment in Clearenv

Browse source 
The comment being removed was added by commit ff3173849e
(which predates Gerrit and Rietveld, so no CL link), and
at the time it made sense.

Since CL 148370043 (and up to the current implementation of Clearenv)
the env map, which is populated by copyenv, is actually used, so the
comment is no longer valid.

It is also misleading, so it's best to remove it.
