processFilelog: improve compatibility with encoding=="raw"

`p4 filelog` may truncate changelist descriptions in multibyte encodings.
Setting p4.encoding = "raw" appears to be an effective workaround, but
p4.run_filelog() breaks under raw encoding, because processFilelog() assumes
the revision object contains strs. This is simple enough to fix.
