lib/igt_debugfs: Add IGT_CRC_SOURCE environmental variable
Adds support for the IGT_CRC_SOURCE environmental variable to make it
easier for drivers to run tests using custom CRC sources.
Example usage:
`IGT_CRC_SOURCE=intf ./kms_pipe_crc_basic`
If the IGT_CRC_SOURCE isn't set, use the original source that was passed
in as a parameter to pipe_crc_new().
