lib/buildid: Fix build ID parsing logic

The parse_build_id_buf does not account Elf32_Nhdr header size
when getting the build id data pointer and returns wrong build
id data as result.

This is problem only for stable trees that merged c83a80d8b84f
fix, the upstream build id code was refactored and returns proper
build id.

lib/buildid: harden build ID parsing logic

[ Upstream commit 905415ff3ffb1d7e5afa62bacabd79776bd24606 ]

Harden build ID parsing logic, adding explicit READ_ONCE() where it's
important to have a consistent value read and validated just once.

Also, as pointed out by Andi Kleen, we need to make sure that entire ELF
note is within a page bounds, so move the overflow check up and add an
extra note_size boundaries validation.

Fixes tag below points to the code that moved this code into
lib/buildid.c, and then subsequently was used in perf subsystem, making
this code exposed to perf_event_open() users in v5.12+.

build-id: require program headers to be right after ELF header

[ Upstream commit 961a2851324561caed579764ffbee3db82b32829 ]

Neither ELF spec not ELF loader require program header to be placed right
after ELF header, but build-id code very much assumes such placement:

See

find_get_page(vma->vm_file->f_mapping, 0);

line and checks against PAGE_SIZE.

Returns errors for now until someone rewrites build-id parser
to be more inline with load_elf_binary().
