patch 8.0.0241: fallback implementation of mch_memmove is unused

patch 8.0.0241: fallback implementation of mch_memmove is unused
Problem: Vim defines a mch_memmove() function but it doesn't work, thus is
always unused.
Solution: Remove the mch_memmove implementation. (suggested by Dominique
Pelle)

3744 * First you create yourself a search context by calling vim_findfile_init(). | |
3745 * It is possible to give a search context from a previous call to | |
3746 * vim_findfile_init(), so it can be reused. After this you call vim_findfile() | |

3748 * returns the next file which matches the conditions given to | |
3749 * vim_findfile_init(). If it doesn't find a next file it returns NULL. | |
3750 * | |
3751 * It is possible to call vim_findfile_init() again to reinitialise your search | |
3752 * with some new parameters. Don't forget to pass your old search context to | |
3753 * it, so it can reuse it and especially reuse the list of already visited | |
3754 * directories. If you want to delete the list of already visited directories | |
3755 * simply call vim_findfile_free_visited(). | |
3756 * | |
3757 * When you are done call vim_findfile_cleanup() to free the search context. | |
