Reduce size of portable Git

[dscho]

It would be really nice if GitHub for Windows could download a substantially smaller PortableGit for Windows 2.x.

I previously already identified locales and most of the terminfo as unnecessary, but that still leaves a lot of room for improvement. My plan is to run the test suite on a current PortableGit, using Process Explorer to identify the list of used files, then generate the negative list and inspect it carefully, extending the list of exclusions as appropriate.

I feel bad that you created this issue while I just recently requested this: git-for-windows/build-extra#68 :(

@shiftkey sorry, I forgot to Cc: you! This was on your wish list, wasn't it?

[shiftkey]

@dscho yes, yes it was! 😁
