Some vendor library doesn't contain the section header. It causes
segmentation fault in `FindElfClassSection`.
> e_shoff:
> This member holds the section header table's file offset in bytes.
> If the file has no section header table this member holds zero.

We do this in a lot of places, but we're inconsistent.
Normalize the code to the Google C++ style guide.

The Breakpad and Crashpad clients will use an object's DT_SONAME as
the name for a module if it exists. Previously, linux dump_syms would
assume the basename of an input elf file matches that value, causing
symbol lookups to fail if they were mismatched. This patch updates
dump_syms to use DT_SONAME as the module name, if present.

It is legal for an ELF to contain multiple PT_NOTEs, and that is in
fact what lld's output looks like.
Testing: "make check" and breakpad_unittests when patched into
chromium.

The layout of Elf32_Nhdr and Elf64_Nhdr is the same, so remove
templating and code that extracts the elfclass from the ELF file.
