Fix bootstrap to remove read-only directories right.

[Ralf Wildenhues]

When an earlier in-tree 'make dist' was interrupted, it may leave behind
a directory automake-$APIVERSION with read-only subdirs, breaking a
subsequent bootstrap.  This trivial patch fixes that.

Pushed to master and branch-1-10.

Cheers,
Ralf
