Subject: [PATCH] build: add -DZLIB_CONST when building with --shared-zlib

Commit 782620f added the define only when building with the bundled
zlib. Using a shared zlib results in build breakage:

../src/inspector_agent.cc:179:16: error: assigning to 'Bytef *' (aka 'unsigned char *') from incompatible type
      'const uint8_t *' (aka 'const unsigned char *')
  strm.next_in = PROTOCOL_JSON + 3;
               ^ ~~~~~~~~~~~~~~~~~
