ptrace_test: eliminate assumption about thread scheduling

Description

ptrace_test: eliminate assumption about thread scheduling

A couple of the ptrace tests make assumptions about which thread in a
multithreaded process will run after a halt. This makes the tests less
portable across branches, and susceptible to future breakage. Instead,
twiddle thread scheduling and priorities to match the tests'
expectation.
