templatekw: make experimental {peerpaths} return a single-level dict (BC)

templatekw: make experimental {peerpaths} return a single-level dict (BC)

This was planned as in c0d8de2724ce, "{peerpaths.default.pushurl} will be
translated to peerpaths['default'].makemap()['pushurl'], which means
{peerpaths} should be a single-level dict and sub-options should be
makemap()-ed."
