Doesn't work with new Xmir binary name

[Robert Ancell]

[Impact]
LightDM doesn't support the new XMir which now has its own binary "Xmir" instead of being an option to the standard X binary. This means that newer versions of XMir will not work with LightDM. It is desirable to SRU the new XMir to older versions of Ubuntu in the future - this change will allow us to do this.

[Test Case]
Run LightDM with type=unity in lightdm.conf. This should work with both the old XMir and new XMir.

[Regression Potential]
Low. The change only affects the "unity" seat type and should have no effect on the default "xlocal" seat type. It has been tested with both the old and new XMir and appears to work fine.
