Update libmaa to 1.4.7:

  Fix incorrect work of set_* where hash function generates full
  ulong_t hash value

  hsh_string_hash generates full 64bit hash value on platforms where
  sizeof(long) == 8

  Improve build and test system

  tests/err: minor fix, target "test" should not remove _mkc_* and .o files

  Avoid trailing \n in format argument for err_* functions, no need
  for it any longer

  tests/err/errtest.c: fix another compilation failure due to __wur
  (warning used result)
