xen: common: Use unbounded array for symbols_offset.

Using a singleton array causes gcc5 to report:
symbols.c: In function 'symbols_lookup':
symbols.c:128:359: error: array subscript is above array bounds [-Werror=array-bounds]
symbols.c:136:176: error: array subscript is above array bounds [-Werror=array-bounds]
