description:
Handle -l which dlopens libs.  This is more applicable to rump_server
than rump_allserver.

So if I do:

golem> rump_server unix:///tmp/commsuck
==>
golem> env RUMP_SERVER=unix:///tmp/commsuck rump.modstat
NAME             CLASS      SOURCE     REFS  SIZE     REQUIRES
suser            secmodel   builtin    0     -        -

and:

golem> rump_server -l librumpvfs.so unix:///tmp/commsuck
==>
golem> env RUMP_SERVER=unix:///tmp/commsuck rump.modstat
NAME             CLASS      SOURCE     REFS  SIZE     REQUIRES
suser            secmodel   builtin    0     -        -
wapbl            vfs        builtin    0     -        -

golem> rump_server -l librumpvfs.so -l librumpfs_ffs.so unix:///tmp/commsuck
==>
golem> env RUMP_SERVER=unix:///tmp/commsuck rump.modstat
NAME             CLASS      SOURCE     REFS  SIZE     REQUIRES
ffs              vfs        builtin    0     -        -
suser            secmodel   builtin    0     -        -
wapbl            vfs        builtin    0     -        -

Well, you get the picture...
