Kevin Enderby 6bc5c395e1 Fix identify_magic() to check that a file that starts with MH_MAGIC is ...

at least as big as the mach header to be identified as a Mach-O file and
make sure smaller files are not identified as a Mach-O files but as
unknown files. Also fix identify_magic() so it looks at all 4 bytes of
the filetype field when determining the type of the Mach-O file.
Then fix the macho-invalid-header test case to check that it is an
unknown file and make sure it does not get the error for
object_error::parse_failed.  And also update the unit tests.
