description:
check-shlibs-macho.awk: Implement revision 1.3 correctly.

Skip any lines of otool output that do not start with a tab, ensuring we
only check valid files and ignore e.g. shell scripts.  Older versions of
otool would simply print no output on such files, whereas newer releases
print "is not an object file".
