Remove -l flag in CGI script

'w3mman -l file' relies on the -l flag of some man implementations, which
ignores system manual sections and assumes any arguments are paths to files. 
It first constructs a URL that gets passed to the w3mman2html.cgi script, which
then checks for a query parameter named 'local' and ultimately opens that file
in w3m after converting the output of '$MAN -l $file', where $MAN is
/usr/bin/man if the W3MMAN_MAN environment variable is unset or an empty
string.

Unfortunately, FreeBSD's man(1) does not have a -l flag, instead checking
arguments against the shell pattern */* to determine whether they're paths or
not.  Consequently, the resulting invocation '/usr/bin/man -l /path/to/file'
will fail with an error that -l is an invalid flag for man(1).

A patch is attached that removes the -l flag in the w3mman2html.cgi script to
fix this issue, resulting in '/usr/bin/man /path/to/file' being executed
instead.
