Felix Geisendörfer 9b0de0854d runtime: fix missing pprof labels 
Use gp.m.curg instead of the gp when recording cpu profiler stack
traces. This ensures profiler labels are captured when systemstack or similar
is executing on behalf of the current goroutine.

After this there are still rare cases of samples containing the labelHog
function, so more work might be needed. This patch should fix ~99% of the
problem.

Also change testCPUProfile interface a little to allow the new test to
re-run with a longer duration if it fails during a -short run.

Fixes #48577.
