externalsrc: Ensure SRCREV is processed before accessing SRC_URI

When SRCREV is used, call bb.fetch.get_srcrev() before accessing
SRC_URI. Without this new bb.fetch.get_srcrev() call, SRC_URI might be
accessed before SRCREV had a chance to be processed.

In master, this is fixed by https://git.yoctoproject.org/poky/commit/?id=62afa02d01794376efab75623f42e7e08af08526
However, this commit is not suited for backport since it is quite invasive.
The part of the commit that fix the bug is:

NB: bb.fetch.get_hashvalue() does not exist in kirkstone but is
equivalent to bb.fetch.get_srcrev().
