git.bat not picked up on dbt deps

ref. #1110

> dbt deps
Encountered an error:
Could not find command, ensure it is in the user's PATH: "git"

I have reasons to wrap my executables. On Windows I wrap my executables in .bat scripts (to get a similar effect to .sh). But then Popen( ['git'] ) doesn't work. Popen( ['git.bat']) works.

So the platform-independent way to get git to work is to use shutil.which to get the full path to the exe. Popen([ which('git') ], ) works.

@majidaldo Just to clarify, you're encountering an error when you run dbt deps?

ah sorry. yes.

Ok! And if I understand your original message, are you saying that you're able to resolve the dbt deps error by changing line 420 below from cmd to shutil.which(cmd)?

...well, depend on how you guys want to structure subprocess calls. The way you have it is that cmd is a list of strings (shell=False). So you'd only need to change the first element in the list: cmd --> [which(cmd[0])] + list(cmd[1:]).

[majidaldo]

FYI, with shell=True, your wouldn't have to use which. You'd have to consider security implications but I think it's safe here.

Ok, this one is a little bit beyond me. @kwigley When you have a moment, could I ask for your sense-check here?

[majidaldo]

bump. this should be straightforward.

@majidaldo Is this a fix you'd be interested in contributing? I'd welcome a PR for it, if you don't mind explaining the system/security implications of the proposed changes.
