Support PE modules in core files when running core2md

Browse source 
Core files generated from `wine` contain both ELF and PE modules. Module
format can be guessed by checking the file contents. If the module
corresponds to PE-file conditions (has specific fields set up as
described in https://code.google.com/archive/p/corkami/wikis/PE.wiki)
we'll create a MDCVInfoPDB70 record in the minidump for it, but if
the file cannot be opened, is too short or is not a PE file, we'll
fall back to ELF procedure.

Added /src/client/linux/minidump_writer/pe_file.{cc,h} to
src_client_linux_libbreakpad_client_a_SOURCES and
src_client_linux_linux_client_unittest_shlib_SOURCES.
Makefile.in and aclocal.m4 were generated by running 'aclocal && automake'.

Test: build core2md and use it to convert a core file into dmp, validate
that the generated dmp file can be opened. Ran './configure & make'.
