base-files: Move IOPSYSWRT-only files to files
We would like to get rid of iop-files, because it makes it hard to merge modifications from OpenWrt and because it causes more confusion than clarity. As a first step, remove all files that exist in iop-files, but not in files.
For the remaining files in iop-files, it has to be decided on a case-by-case basis, whether to delete the file entirely in case the changes are no longer needed or whether to incorporate the changes done in the iop-files-version of the file into the one in files.
The remaining files are:
- iop-files/etc/init.d/led
- iop-files/etc/init.d/sysctl
- iop-files/etc/banner
- iop-files/etc/inittab
- iop-files/etc/passwd
- iop-files/etc/shadow
- iop-files/lib/preinit/99_10_failsafe_login
- iop-files/usr/libexec/login.sh
