Add linux alternative for otool/lipo tools in mach-o comparator

The mach-o comparator use otool/lipo tools which are not available on debian (only in MACOSX), thus comparing Mach-O files on linux will return unusable binary diff with message: │┄ 'lipo' not available in path. Falling back to binary comparison.

It's possible to parse this file on linux, see: https://stackoverflow.com/questions/8712352/linux-mach-o-disassembler

or by using the radare2 disassembler: https://reverseengineering.stackexchange.com/a/14303
