Fix window workspaces in drun mode.

Previously, tofi-drun would print the filename of the selected
.desktop file to stdout. This could then be passed to
`xargs swaymsg exec gio launch` to be executed.

The problem is that this ends up defeating the purpose of passing the
command to swaymsg exec, and the workspace the command was selected on
may not be the one that it starts up on, if for example it takes a long
time and the user switches workspaces in the meantime.

The solution is to instead print the Exec= line from the .desktop file,
and pass that directly to `xargs swaymsg exec --` for execution.

To avoid too much breaking of configs for the few people who use tofi
currently, this commit adds a new option, --drun-print-exec, to enable
the fixed behaviour. A future release will change this to be the
default, however.
