util: Query build-id by symbol address, not library name
This patch renames build_id_find_nhdr() to
build_id_find_nhdr_for_addr(), and changes it to never examine the
library name.
Tested on Fedora by confirming that build_id_get_data() returns the same
build-id as the file(1) tool. For BSD, I confirmed that the API used
(dladdr() and struct Dl_info) is documented in FreeBSD's manpages.
This solves two problems:
- We can now the query the build-id without knowing the installed library's
filename.
This matters because Android requires specific filenames for HAL
modules, such as "/vendor/lib/hw/vulkan.${board}.so". The HAL
filenames do not follow the Unix convention of "libfoo.so". In
other words, the same query code will now work on Linux and Android.
- Querying the build-id now works correctly when the process
contains multiple shared objects with the same basename.
(Admittedly, this is a highly unlikely scenario).
