[esan] Initialize runtime during early interceptors

Description

[esan] Initialize runtime during early interceptors

Summary:
Adds initialization of esan's runtime library during any early interceptors
that are sometimes called prior to the official __esan_init() invocation
(we see this with apps using tcmalloc).

Adds handling of interceptors called during interceptor initialization.
