msetup: Update options when builddir is already configured

`meson setup -Dfoo=bar builddir` command was returning success ignoring
new option values.

This now also update options. It is useful because it means
`meson setup -Dfoo=bar builddir && ninja -C builddir` works regardless
whether builddir already exists or not, and when done in a script,
changing options in the script will automatically trigger a reconfigure
if needed. This was already possible by always passing --reconfigure
argument, but that triggers a reconfigure even when options did not
change.
