Further refinements to "kill other thread".

Switched from SIGSEGV to SIGSTKFLT.  Otherwise it looks like we're
seg-faulting in code that was actually executing just fine.

Ignore SIGSEGV before returning.  This avoids creating a second dump
when dvmAbort() is called.  (If the caller's stack trace were at all
interesting, we wouldn't be here, and we can do without the log spam.)

Added some more details to the logging.

For bug 2517042.
