libsrt library link fails on some platforms due to assumed lib path from srt dependency

[jsbohnert]

The library specified in binding.gyp assumes that the libsrt.a file generated by the srt dependency will be present in the folder deps/build/lib/.

Depending on the exact platform used to build the project, this can be a different name. In my case (CentOS 7 64bit Linux), the srt dependency installs to deps/build/lib64/ and the build of node-srt fails:

> @eyevinn/srt@0.4.0 rebuild /home/james/code/srt4w/subprojects/node-srt
> $(npm bin)/node-gyp rebuild -j $(echo "console.log(require('os').cpus().length)" | node)

Within the srt project the actual folder used is defaulted from CMake's GNUInstallDirs defaults for the platform, if not configured deliberately.
