sandbox: hostfile: fix UB-inducing shift
On 32-bit hosts, UBSan reports:
====================================================================
UBSAN: Undefined behaviour in ./arch/sandbox/board/hostfile.c:135:12
shift exponent 32 is too large for 32-bit type 'long unsigned int'
====================================================================
Fix this by using a unsigned long long for base. The upper 32-bit
won't be set, but device tree fixups can now read them.
