Move wait-for-reconnection logic inside ard-reset-arduino

When a Leonardo based board is reset, the port disappears and we need to
wait till it comes back.

Earlier this logic was handled by a separate shell script. Now the logic
is moved inside the ard-reset-arduino perl script. This is done to
reduce the number of binaries that are needed by the makefile.

Fix #95
