[PATCH] base.bbclass: make do_fetch depends on PREMIRRORS MIRRORS

[<changqing.li@windriver.com>]

From: Changqing Li <changqing.li@windriver.com>

When there are tarballs in local mirror file://, do_fetch will
create symlink under DL_DIR, eg:
pseudo-prebuilt-2.33.tar.xz -> /project/path/to/localmirrorA/pseudo-prebuilt-2.33.tar.xz
after user update path from localmirrorA to localmirrorB, because
do_fetch don't depends on PREMIRRORS/MIRRORS, do_fetch will not
be rerun, so the symlink will not update to:
pseudo-prebuilt-2.33.tar.xz -> /project/path/to/localmirrorB/pseudo-prebuilt-2.33.tar.xz
then, do_upack will failed since the tarball cannot be found.
