[PATCH] perf: Add missing sys/types.h include

From: Jesus Sanchez-Palencia
Date: Wed Jan 04 2023 - 13:23:22 EST


Not all libc implementations define ssize_t as part of stdio.h like
glibc does since the standard only requires this type to be defined by
unistd.h and sys/types.h. For this reason the perf build is currently
broken for toolchains based on uClibc, for instance.

Include sys/types.h explicitly to fix that. This is a follow up to
commit 378ef0f5d9d7 ("perf build: Use libtraceevent from the system").
