Merge branch 'releases/v0.11.0'

* Revert "Quick fix for relocation issues."

This reverts commit 57608a6dc4.

* Buildcache: relocate fixes (#6512)

* Updated function which checks if a binary file needs relocation.
  Previously this was incorrectly identifying ELF binaries as symbolic
  links (so they were being excluded from relocation). Added test to
  check that ELF binaries are not considered symlinks.

* relocate_text was not replacing paths in text files. Added test to
  check that text files are relocated properly (i.e. paths in the file
  are converted to the new prefix).

* Exclude backup files created by filter_file when installing from
  binary cache.

* Update write_buildinfo_file method signature to distinguish between
  the spec prefix and the working directory for the binary cache
  package.
