Fix build error for unit test (#473)

Fix the compile error with the following command:
`make all-with-unit-tests SERVER_CFLAGS='-Werror -DSERVER_TEST'
`

```
/usr/bin/ld: /home/ubuntu/valkey-shiv-repo/valkey/src/eval.c:1172: undefined reference to `lua_next'
/usr/bin/ld: /home/ubuntu/valkey-shiv-repo/valkey/src/eval.c:1154: undefined reference to `lua_toboolean'
/usr/bin/ld: /home/ubuntu/valkey-shiv-repo/valkey/src/eval.c:1175: undefined reference to `lua_type'
/usr/bin/ld: /home/ubuntu/valkey-shiv-repo/valkey/src/eval.c:1176: undefined reference to `lua_tonumber'
collect2: error: ld returned 1 exit status
make[1]: *** [Makefile:469: valkey-unit-tests] Error 1
make[1]: Leaving directory '/home/ubuntu/valkey-shiv-repo/valkey/src'
make: *** [Makefile:6: all-with-unit-tests] Error 2
```

Issue is happened as all deps libraries not linked for
valkey-unit-tests, so linked all libraries to the binary.
