This fix normalize paths when reading the .dockerignore file by removing
leading slashes.

This fix tries to address issues related to #23221 where Dockerignore

This fix skips the UTF-8 BOM bytes from the beginning of the
Dockerignore if exists.
Additional tests has been added to cover the changes in this fix.
