someblocks.c: Add support for dwlb

Adds option '-b' to support dwlb bar: https://github.com/kolunmi/dwlb
If this option is selected, a socket will be opened to communicate with
dwlb status bar and status text will be written here.

 # patches
 Here are some patches to someblocks that add features that I either don't want to merge in, or that require a dwl/somebar patch to work.
 I do not maintain these but I will take pull requests to update them.
+# dwlb
+To run and output status to dwlb, use 'someblocks -b'
