[PATCH RESEND stable 5.4] perf tools: Fixup get_current_dir_name() compilation

[Florian Fainelli]

From: Alexey Dobriyan <adobriyan@xxxxxxxxx>

commit 128dbd78bd673f9edbc4413072b23efb6657feb0 upstream

strdup() prototype doesn't live in stdlib.h .

Add limits.h for PATH_MAX definition as well.

This fixes the build on Android.

This patch is necessary to build perf with a musl-libc toolchain, not
just Android's bionic.

Resending because missed stable the first time
