patch: alpha

Allow dwm to have translucent bars, while keeping all the text on it
opaque, just like the alpha patch for st.

By default dwm might make windows' borders transparent when using
composit window manager (e.g. xcompmgr, picom).  Alpha patch allows to
make borders opaque.  If all you want is to make borders opaque, you
don't care about statusbar opacity and/or have problems applying alpha
patch, then you might use fixborders patch instead.
