Make transition to "postinstall" domain explicit.

When running the postinstall program, we were relying on the automatic
transition between update_engine domain and postinstall, which required
postinstall_file to be an entrypoint for such domain. This patch makes
the transition explicit by calling setexeccon(3).

Bug: 28008031
TEST=make dist; Deployed an update to edison-eng: postinstall runs as "postinstall" domain.
