bloblist: adjust default bloblist size after reloc

If neither CONFIG_BLOBLIST_FIXED NOR CONFIG_BLOBLIST_ALLOC is set,
currently CONFIG_BLOBLIST_SIZE_RELOC defaults to 0 except if
* CONFIG_ARM=y && CONFIG_EFI_LOADER=y && GENERATE_ACPI_TABLE=y.

A size of zero never makes sense for a bloblist.

When using QFW we need more than 64 KiB to host the ACPI table.
In this case CONFIG_BLOBLIST_ALLOC is used.

Set a reasonable default.

Remove the CONFIG_BLOBLIST_SIZE_RELOC in ARM QEMU defconfigs which are
not compatible with ACPI tables passed from QEMU.
