Commit 54d3d94b6e ("support/download: print
command used for download") broke the git and svn download helpers, because
these helpers have invocations of the _git/_svn commands where the exact
output matters.
For example for git, this would result in:
date: invalid date ‘GIT_DIR=.../dl/libyuv/git/.git git log -1 --pretty=format:%ci \n2019-04-12 17:48:45 +0000’
Detected a corrupted git cache.
Removing it and starting afresh.
Fix by splitting the _git function in two: _git and _plain_git.
The former echoes the command, and then calls the latter.
Most invocations use _git as before, but those cases where the output should
not be disturbed, directly call _plain_git.
For symmetry, all download helpers are aligned, even though only the git and
svn helpers were broken.
