Manual rocprof join breaks in ROCm 5.2.x

[coleramos425]

I noticed that profiling applications in ROCm 5.2.x causes issues. A peak at verbose debug logs shows
that we crash when checking for arch_vgpr and accum_vgpr (two counters added in ROCm 5.3).

It's not the concern I expressed in the original ticket (#117 (comment)), but it'll be an easy fix
