mrb makeDeps (md) is broken

[lgarren]

mrb md produces an error. It hasn't been exercised in some time, so this is not a big surprise.

[garren@scisoftbuild01 build_slf7.x86_64]$ mrb md
Traceback (most recent call last):
  File "/scratch/products/mrb/v5_19_05/libexec/makeDep.py", line 285, in 
    system.run()
  File "/scratch/products/mrb/v5_19_05/libexec/makeDep.py", line 104, in run
    self.load_project_dependency_database()
  File "/scratch/products/mrb/v5_19_05/libexec/makeDep.py", line 135, in load_project_dependency_database
    if not self.project_deps.has_key(pkg):
AttributeError: 'dict' object has no attribute 'has_key'

To Reproduce
checkout larsoft and build
in the build directory, type "mrb md"

It looks like I can fix this simply by running 2to3.

[lgarren]

Um, apparently not. The resulting file is far from complete.

[lgarren]

mrb makeDep.py is a) written in python 2 and b) not compatible with mrb 5. I am able to run it successfully with mrb 4 if I do the following:

mrb b
unsetup python
unsetup sqlite
setup python v2_7_15a
mrb md

Because the larsoft base_dependency_database file has not been updated since Jan. 2019 (and contained references to larsimobj!), I have updated the head of develop with a base_dependency_database file from the larsoft v09_30_00 release.

Here's hoping we can come up with a better solution.
