CharEncodingCheckPlugin: Remove Noisy Print

Currently, CharEncodingCheckPlugin prints a message for every
file that passes the test, which for some platforms can cause
most of the CI build log to be filled with this print. It does
not add any value, so this patch removes the noisy print and
only prints if the encoding check fails.
