dbscripts: fix createlinks for binaries in non-standard locations

In FS#79592 we encountered yet another case where sogrep was not able to detect the necessary rebuild because the binaries reside in the non-standard path "/usr/share/$pkgname/bin/" which is currently not taken into account.

This commit fixes this behaviour by also unpacking files symlinked from one of the standard locations.
