[OE-core] [PATCH V2] insane.bbclass: skip opening symlinks in package_qa_check_libdir

[Yi Zhao]

If the library is installed in a non-standard location and don't set
INSANE_SKIP, e.g. libfoo.so is installed in /usr/local/lib. The
package_qa_check_libdir will cause a traceback because it will try to
open the .so link in package-dev to check if it's an ELF:
The stack trace of python calls that resulted in this exception/failure
was:
File: 'exec_python_func() autogenerated', lineno: 2, function: <module>
     0001:
 *** 0002:do_package_qa(d)
     [snip]
     0048:    def open(self):
 *** 0049:        with open(self.name, "rb") as f:
     0050:            try:
     0051:                self.data = mmap.mmap(f.fileno(), 0, access=mmap.ACCESS_READ)
     0052:            except ValueError:
     0053:                # This means the file is empty
Exception: FileNotFoundError: [Errno 2] No such file or directory:
'/buildarea1/build/tmp/work/i586-poky-linux/foo/1.0-r0/packages-split/foo-dev/usr/local/lib/libfoo.so'

For .so sysmlinks, we don't need to open it and report it directly.
