[PATCH] t9010: svnadmin can fail even if available

[Jonathan Nieder <jrnieder@gmail.com>]

If svn is built against one version of SQLite and run against
another, svnadmin (needlessly) errors out during t9010:

 <<< Started new transaction, based on original revision 1
      * adding path : branches ... done.
      * adding path : trunk ... done.
 svnadmin: Couldn't perform atomic initialization
 svnadmin: Couldn't perform atomic initialization
 svnadmin: SQLite compiled for 3.7.4, but running with 3.7.3

Work around this by putting the svn invocations into a single test
that builds a repo to compare the test-svn-fe result against.  This
test would always pass but only set the new SVNREPO test prereq if svn
succeeds; and the test using that repo gets an SVNREPO prerequisite so
it only runs with working svn installations.

This seems like the right thing to, anyway: the test script is meant
to test the version of git just built, not the installed svn.

As a side effect, earlier tests will run now even if svn is not
installed.  Remove the svn_cmd () helper to decrease the temptation to
run svn from those tests.
