getdeps: allow overriding project source, build, and install directories

Browse Source 
Summary:
Add arguments to getdeps.py to allow overriding the source, build, and install
directories a per-project basis.  The arguments take the form `[PROJECT:]PATH`
If the `PROJECT` portion is omitted, it defaults to the current project being
built.

In particular this makes it possible to specify `--src-dir .` to tell
getdeps.py to find the project sources from the current directory rather than
downloading them.
