Update comments regarding use of the hard coded dhcpcd -L command line option.current-20210227

The -L command line option was added to the dhcpcd call in the -current
development cycle to assist ARM users with getting networking up and running.
This addition was incorrect as rc.inet1 already has support to use or not use
-L by setting DHCP_NOIPV4LL[x]="".  When I was updating rc.inet1 I took out
the -L, but didn't make it clear enough why I had taken it out and how to use
the DHCP_NOIP4ALL[x]="" option in rc.inet1.conf.  This commit is simply
updating that comment to be more verbose.
