image.c: Avoid potential compile error

gcc 11.2.1 with -pedantic:
image.c: In function ‘__imlib_LoadImage’:
image.c:567:9: error: a label can only be part of a statement and a declaration is not a statement [-Werror=pedantic]
  567 |         ImlibLoader ** loaders = __imlib_GetLoaderList();

clang 13.0.0:
image.c:567:9: error: expected expression
        ImlibLoader ** loaders = __imlib_GetLoaderList();
        ^

Also remove pointless self-assignment.
