dbStaticLib: fix dbGetStringNum reading UINT64 through a 32-bit pointer

Browse Source 
The DBF_UINT64 case dereferenced the 8-byte field as *(epicsUInt32 *),
reading only its low 32 bits, so large UINT64 values printed wrong
(e.g. 0x1_0000_0000 as "0") and save/restore round-tripping broke.  Cast
to epicsUInt64*, matching the adjacent DBF_INT64 case.
