Bug 984811

As is the case with a very old cartridge, if both
OPENSHIFT_POSTGRES_VERSION and OPENSHIFT_POSTGRESQL_VERSION do
not exist in postgresql/env directory, create one with '8.4'.

Hard coding this value should be OK, since 8.4 was the only supported
version of PostgreSQL for the cartridge this condition ever applies.

Use oo_spawn for all root scoped shell commands

Revert previous changes which replaced oo_spawn calls with ApplicationContainer.run_in_root_context.

The oo_spawn method was intentionally designed to be the single execution path for all shell executions,
for security and clarity. Adding a second execution path to oo_spawn not only results in multiple ways
to do the same thing, but having such a method in ApplicationContainer specifically promotes creating
unwarranted/undesirable dependencies on ApplicationContainer where no dependency was previously
necessary.
