pkg-config protobuf --version needs to be pkg-config protobuf --nodversion

Describe the bug
./configure.js spills out

[...]
[tilemill configure] Could not configure TileMill because "pkg-config protobuf --version" returned an error (pkgconf: --version specified with other options or module names, assuming --modversion.)

This does come from a run of pkg-config protobuf --version:

pkgconf: --version specified with other options or module names, assuming --modversion.
3.7.0

Instead, pkg-config protobuf --modversion should be executed:

3.7.0

Environment: (Note: We are not setup to test on Linux or Windows so help may be slower on those OSs)

• OS & Version: Arch/ Artix Linux
• Node Version [e.g. v8.15.0] node --version: v11.15.0

To Reproduce

• git clone git://github.com/tilemill-project/tilemill.git
• cd tilemill
• ./configure.js

Expected behavior
./configure.js finishes without error messages.
