[Buildroot] [PATCH 47/51] arc/xtensa: get rid of an intermediate blind kconfig option

[Yann E. MORIN]

It is not needed to have an intermediate blind option, we can just
hide the prompt behind the same dependency as the non-blind symbol.

Update our qemu-xtensa defconfig acordingly (note: it was using
different values for both options, which is not possible; the blind
option was just set to the non-blind one in the .config).

Also remove an unneeded empty default for the BR2_XTENSA_OVERLAY_DIR
string option (strings are empty by default).
