Michael Trent d891699e6f Detect malformed LC_LINKER_COMMANDs in Mach-O binaries ...

Summary:
llvm-objdump can be tricked into reading beyond valid memory and
segfaulting if LC_LINKER_COMMAND strings are not null terminated. libObject
does have code to validate the integrity of the LC_LINKER_COMMAND struct,
but this validator improperly assumes linker command strings are null
terminated.

The solution is to report an error if a string extends beyond the end of
the LC_LINKER_COMMAND struct.
