Subject: [PATCH] perf auxtrace: Include sys/types.h for pid_t

In 754187ad73b73bcb ("perf build: Remove NO_AUXTRACE build option")
sys/types.h was removed, which broke the build in all Alpine Linux
releases, as musl libc has pid_t defined via sys/types.h, add it back.

Fixes: 754187ad73b73bcb ("perf build: Remove NO_AUXTRACE build option")
