tests: don't use mkcommit shell function in test-divergent.t

Upcoming series will start merging commit descriptions while resolving
content-divergence. This tests are here to test the basics of content-divegrence
resolution and we should not be testing much of commit description merge here.

Replacing mkcommit function with normal hg calls will help us decide on the
commit messages ourselves and prevent conflicts while merging commit messages.

Basic test of divergence: two divergent changesets with the same parents
With --all --any we dedupe the divergent and solve the divergence once

  $ hg init test1
  $ cd test1
  $ echo a > a
  $ hg ci -Aqm "added a"
  $ echo b > b
  $ hg ci -Aqm "added b"

  $ hg up .^
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ echo bdivergent > bdivergent1
  $ hg ci -Am "divergent1"
  adding bdivergent1
  created new head

  $ hg up .^
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ echo bdivergent > bdivergent2
  $ hg ci -Am "divergent2"
  adding bdivergent2
  created new head

  $ hg prune -s "desc(divergent1)" "desc('added b')"

Test divergence resolution when it yields to an empty commit (issue4950)
cdivergent2 contains the same content than cdivergent1 and they are divergent
versions of the revision _c
