[OE-core] [PATCH 01/10] gen-lockedsig-cache: ensure symlinks are dereferenced

[Paul Eggleton]

If you set up a local mirror in SSTATE_MIRRORS then you can end up with
symlinks in SSTATE_DIR rather than real files. We don't want these
symlinks in the sstate-cache prodcued by gen-lockedsig-cache, so
dereference any symlinks before copying.
