(PUP-1099) Fix incorrect permissions in RPMs

The RPM spec template uses extremely restrictive permissions for `log`
and `lib` directories. These permissions were being incorrectly applied to
`examples` during packaging. This corrects that problem by resetting
default attributes after restricting `log` and `lib` directories.
