[Bug-vc-dwim] [PATCH 1/2] build: tell bootstrap to check build/test requirements

[Jim Meyering]

I noticed 3 test failures when ctags was not installed,
and even more when tools like cvs, svn, hg, bzr were not installed.
That prompted this first change.

Also, the new author-bzr test was failing on a bare system
on which I had not yet run bzr whoami to set my name/email info.
The second patch fixes that test not to rely on such set-up.
