[libbacktrace] Fix .gnu_debugaltlink build-id check

The 'debugaltlink_name_len =+ 1' bug reported in PR89136 exposes the fact that
the build-id is not verified for the .gnu_debugaltlink.

Fix both problems.

PR libbacktrace/89136
* elf.c (elf_add): Read build-id if with_buildid_data.  Fix
'debugaltlink_name_len =+ 1'.
