[Impact]
LightDM doesn't close the server side end of the pipes used to communicate with session processes and greeters. This means each session/greeter that is created leaks two file descriptors eventually leading to the system stopping it from creating new pipes.

[Test Case]
1. Start LightDM
2. Check how many pipes are open
# lsof -p {lightdm_pid} | grep FIFO | wc -l
3. Create sessions by either cycling between users in Unity Greeter or logging in and out
4. Check how many pipes exist using step 2.
Expected result:
No more pipes should be open
Observed result:
Many pipes remain open

[Regression Potential]
Low. Fix is to close pipes when finished with them. Tested with regression tests.
