runtime: Fix GDB integration with Python 2
A similar fix was applied in 545686857bc4c2e7a5306d97e5ef48f631d277bc
but another instance of 'pc' was missed.
Also adds a test for the goroutine gdb command.
It currently uses goroutine 2 for the test, since goroutine 1 has
its stack pointer set to 0 for some reason.
