array.c: steal shared array's container when ARY_SHARED_NUM == 1

array.c (rb_ary_modify): steal shared array's container when
ARY_SHARED_NUM == 1. [Feature #6638]
- Do not allocate new memory in rb_ary_modify when ARY_SHARED_NUM == 1
  and length almost same.
- Store ARY_CAPA instead of RARRAY_LEN in ary_make_shared, to make
  it useful.
- Fix rb_ary_sort_bang accordantly.
