Allow --reconfigure and --wipe of empty builddir

meson setup --reconfigure builddir and meson setup --wipe builddir are now accepting builddir/ to be empty or containing a previously failed setup attempt. Note that in that case previously passed command line options must be repeated as only a successful build saves configured options.

This is useful for example with scripts that always repeat all options, meson setup builddir --wipe -Dfoo=bar will always work regardless whether it is a first invocation or not.
