[PATCH] efi_loader: move efi_var_seed.o to objtree

[Jon Mason]

With commit bd3f9ee679b4d1456d0d3c261ab76788950e6096
(kbuild: Bump the build system to 6.1), there is an issue when trying to
build out of tree, where efi_var_seed.S wants ubootefi.var to be in the
object tree, but lib/efi_loader/efi_var_seed.o wants ubootefi.var to be
in the source tree.

If we change efi_var_seed.o to look in the objtree, then it should work
in both local and out-of-tree.  However, it would require anything
previously working to put ubootefi.vars to the objtree, but it's broken
now anyway.
