Fixes#3377.
The sleep lock file descriptor was immediately closed after it was
acquired due to the dbus message being freed. Now the fd is duplicated
before the message is freed so the inhibitor stays active.
The wl_event_source_fd_update docs say:
> File descriptors are usually writable to begin with, so they do not need to
> be polled for writable until a write actually fails. When a write fails,

So we should only poll for WL_EVENT_WRITABLE if a write fails. I'm not yet sure
how to do this properly and Weston doesn't do it, so in the meantime I'll just
fix the busy loop. I'll ask them too.

It's better to use DT_RPATH dynamic section of the elf binary to store
the paths of libraries to load instead of overwriting LD_LIBRARY_PATH
for the whole environment, causing surprises. This solution is much more
transparent and perfectly suitable for running contained installations
of wayland/wlroots/sway.
The code unsetting the LD_LIBRARY_PATH/LD_PRELOAD was also deleted as
it's a placebo security at best - we should trust the execution path
that leads us to running sway, and it's way too late to care about those
variables since we already started executing our compositor, thus we
would be compromised anyway.
Swayidle handles idle events and allows
for dpms and lockscreen handling. It also
handles systemd sleep events, and can
raise a lockscreen on sleep
