[jsk_rosbag_tools] set python_interpreter python2 for melodic, install scipy<1.9.0+numpy>=1.21.0 for python3 and apt scipy+numpy<1.21.0 for python2

[knorth55]

this PR solves #1780
typeDict is deprecated in numpy>=1.21.0 in scipy

For python3, I install scipy in catkin_virtualenv to upgrade scipy.

scipy version should be 1.9.0 because of openblas problem with meson.
scipy/scipy#16308

For python2, I install numpy<1.21.0 to avoid attribute error.

So I made two requirements for python2 and python3.

• python3:
  • scipy<1.9.0 (because of meson build error)
  • numpy>=1.21.0 (scipy requires this version)
• python2
  • scipy from apt
  • numpy<1.21.0(because of typeDict attribute error)

this PR also specify the python interpreter as python2 for melodic.

This PR passed all tests.
This PR fixes the build error of master branch reported in #1780.

I update this PR.
I found that scipy<1.9.0 needs numpy>=1.21.0, and numpy>=1.21.0 only supports python3.

So I made two requirements for python2 and python3.

• python3:
  • scipy<1.9.0 (because of meson build error)
  • numpy>=1.21.0 (scipy requires this version)
• python2
  • scipy from apt
  • numpy<1.21.0(because of typeDict attribute error)
