[PATCH 4/4] perf symbol: Add missing libgen.h include to get basename() prototype

[Arnaldo Carvalho de Melo]

From: Arnaldo Carvalho de Melo <acme@xxxxxxxxxx>

This works in some places because there are tricks to prefer a GNU
version instead of the XPG version, but started breaking in some musl
libc systems due to some unrelated change that made libgen.h stop being
included by chance.

Since symbol.h is using basename(), make it include libgen.h.
