package/libvirt: fix dependencies in Config.in

Drop spurious "depends on WCHAR" added with commit
ccfc90e1010e42e6529afae3a5ea8bf7226dabc1 and adds missing wchar comment

While at it, drop BR2_USE_MMU from comment as it is already added by
BR2_PACKAGE_LIBVIRT_ARCH_SUPPORTS and fix indentation before
(BR2_TOOLCHAIN_HEADERS_AT_LEAST_4_11 || !BR2_aarch64))
