lib/bb/fetch2: ignore remote URIs when doing file checksums

Skip evaluating remote URIs when doing local file checksums, because we
don't need to process them and doing so will trigger a parse failure if
SRCREV is not fully specified. Whilst this is just delaying a check
until runtime (when do_fetch runs for the recipe) we're only validating
this here accidentally and if we did wish to check it during parsing it
ought to be done explicitly.

Fixes [YOCTO #2512]
