PATCH 1/1 target-finalize: avoid stripping kernel modules with incorrect permissions

If a kernel module is installed with incorrect permissions (0755 iso 0644), it would get stripped in a way that would render the kernel module broken. While the incorrect permissions are a developer error, it is a minor change to prevent this mistake from causing incorrectly stripped modules.

This was reported with bug #6992:

The *.ko is a bit lost between the others, so maybe add a comment to
explain why libpthread*.so* and *.ko are excluded.

But that's optional and may be a separate patch, hence my Ack on this
one already.

Regards,
Arnout
