FTBFS on python2 removal

[Mitsuya Shibata]

mozc cannot build current focal because /usr/bin/python is removed.

Upstream of mozc package doesn't prepare to support python3 yet.
I attach patch which just use "/usr/bin/python2" instead of "/usr/bin/python" on build package.

Could you sponsor it?

[Gunnar Hjalmarsson (gunnarhj)]

Thanks for the fix! Sponsored to focal.

This bug was fixed in the package mozc - 2.23.2815.102+dfsg-8ubuntu1

---------------
mozc (2.23.2815.102+dfsg-8ubuntu1) focal; urgency=medium

  * Add d/patches/workaround_python2.patch
    Use "python2" explicitly in gyp scripts to workaround for focal
    (LP: #1864290).
