app_update: fix test failure for get_app_elf_sha256 test
Commit updated esp_ota_get_app_elf_sha256 to store and return
X number of bytes of the hash, but the test case still expected 64 bytes.
Updated test case to use CONFIG value for expected length.

char dst[sha256_hex_len + 2];
const char fill = 0xcc;
