[PATCH 1/2] passmenu: allow users to override default tool choices

[sternenseemann]

There are multiple different tools users may want to choose for both the
dmenu-like menu program and the xdotool-like “type program” (which we
use for --type).

Especially in the case of dmenu, there are many compatible alternatives
like demnu-wl or bemenu.

For the “type program” there are more or less two alternatives for
wayland we may want to support: ydotool which we currently use, but
employs /dev/uinput, and wtype which has some limitations regarding
Xwayland. Note that as of this commit we would *not* invoke wtype in
a way that works, so wtype support is still pending.
