Ian Rogers 2e6e208825 perf symbol-minimal: Fix ehdr reading in filename__read_build_id 
[ Upstream commit ba0b7081f7 ]

The e_ident is part of the ehdr and so reading it a second time would
mean the read ehdr was displaced by 16-bytes. Switch from stdio to
open/read/lseek syscalls for similarity with the symbol-elf version of
the function and so that later changes can alter then open flags.

Fixes: fef8f648bb ("perf symbol: Fix use-after-free in filename__read_build_id")
