[honister][PATCH] crate-fetch: fix setscene failures

From: Richard Purdie <richard.purdie@linuxfoundation.org>

In sstate.bbclass, when fetching an sstate object we have:

pstaging_fetch(sstatefetch, d):
[...]
localdata.setVar('SRCPV', d.getVar('SRCPV'))

i.e. some code which expands SRCPV before it changes SRC_URI for the sstate
tarball fetching. In crate-fetch.bbclass we have:

def import_crate(d):
import crate
if not getattr(crate, 'imported', False):
bb.fetch2.methods.append(crate.Crate())
crate.imported = True

def crate_get_srcrev(d):
import_crate(d)
return bb.fetch2.get_srcrev(d)

SRCPV = "${@crate_get_srcrev(d)}"

and so an "import crate" occurs when pstating_fetch() is called. That succeeds
and all is well but the bb.fetch2.get_srcrev(d) call fails since there is no url
in SRC_URI which supports srcrev() resulting in:

| WARNING: rust-cross-core2-32-musl-1.54.0-r0 do_deploy_source_date_epoch_setscene: ExpansionError('SRCPV', '${@crate_get_srcrev(d)}', FetchError('SRCREV was used yet no valid SCM was found in SRC_URI', None))
