Cleanup deps_info.json. NFC.

- SDL_getenv: was removed from JS in #12319
- getenv: was removed from JS in #11885
- getlogin: depends on getenv so used to require JS?
- emscripten_log: does not use strlen
- syslog: I can find no evidence of this ever existing in JS
- __ctype_b_loc: implemented in pure C
- __ctype_tolower_loc: implemented in pure C
- __ctype_toupper_loc: implemented in pure C
- calloc/realloc: implemented in pure C
- freopen: can't tell why this was ever in here
- tmpnam: can't tell why this was ever in here
- freelocale/freeaddrinfo: implemented in pure C
- newlocale: implemented in pure C
- realpath: implemented in pure C
- strerr: implemented in pure C
