src: add BoringSSL EVP enumeration fallback
BoringSSL declares EVP_CIPHER_do_all_sorted and EVP_MD_do_all_sorted, but stock no-decrepit builds do not provide those symbols. Add a Node build flag that keeps ncrypto and its dependents on a local BoringSSL fallback list when libdecrepit is absent. Keep embedders that provide the EVP enumeration symbols on the normal OpenSSL-compatible path, matching Electron's patched BoringSSL build.
