Fix scenic-report on large coredump

Fix too many program headers error on certain large coredumps generated by Switcher. Should fix issue #32 (closed).

Report script uses file utility to find original binary_image file path. On large core file, file utility returns error too many program headers. To allow to analyze a large coredump, we need to override elf_pnum default valut of 128 (ELF prog sections processed) with argument -Pelf_phnum=100000.
