openlineage, common.io: convert non-absolute file path to prevent namespace explosion

[mobuchowski]

When receiving malformed file assets with non-absolute paths, converted assets will contain file name in namespace. This does not match OL naming scheme and can cause explosion in namespace table size for OpenLineage users.

Fixes OL issue: OpenLineage/OpenLineage#3557

This causes an error in main:

FAILED providers/amazon/tests/unit/amazon/aws/hooks/test_s3.py::TestAwsS3Hook::test_download_file_with_preserve_name_exposes_lineage - AssertionError: assert 0 == 1

Looking into it
