runtime/pprof: fix goroutine leak profile tests for noopt
The goroutine leak profile tests currently rely on a function being
inlined, which results in a slightly different representation in the
pprof proto. This function is not inlined on the noopt builder.
Disable inlining of the one function which could be inlined to align but
the regular and noopt builder versions of this test. We're not
interested in testing the inlining functionality of profiles with this
test, we care about certain stack frames appearing in a certain order.
This also simplifies a bunch of the checking in the test.
