Use valid `ec` for postponed job.
Postponed job can be registered from non-Ruby thread, which means
`ec` in TLS can be NULL. In this case, use main thread's `ec` instead.
See https://github.com/ruby/ruby/pull/4108
and https://github.com/ruby/ruby/pull/4336

Avoid assert failure when NULL EC is expected
After 5680c38c75aeb5cbd219aafa8eb48c315f287d97, postponed job APIs now
expect to be called on native threads not managed by Ruby and handles
getting a NULL execution context. However, in debug builds the change
runs into an assertion failure with GET_EC() which asserts that EC is
non-NULL. Avoid the assertion failure by passing `false` for `expect_ec`
instead as the intention is to handle when there is no EC.
Add a test from John Crepezzi and John Hawthorn to exercise this
situation.
