[PATCH v4 01/18] perf trace: Include the headers declaring pid_t, strcmp and assert

[Ian Rogers <irogers@google.com>]

trace_augment.h uses pid_t in the augmented_syscalls__set_filter_pids()
prototype and in the !HAVE_BPF_SKEL stub. bpf_trace_augment.c calls
strcmp() in augmented_syscalls__find_by_title() and assert() in
augmented_syscalls__create_bpf_output(), but neither pulls in the header
that declares what it uses. Both happen to build today only because
something else in the include chain drags <sys/types.h>, <string.h> and
<assert.h> in first, which is not guaranteed and does not hold on libcs
such as musl that keep the POSIX namespaces strictly separated.

Include <sys/types.h>, <string.h> and <assert.h> explicitly.
