perf tools: include missing pthread.h header

pthread variables are used in some files without explicitely including
pthread.h. This leads to compile errors on Android. e.g.: in annotate.h,
error: unknown type name 'pthread_mutex_t'

Including pthread.h explicitely in files that use it to have all definitions
included.
