Prevent use of ORowSetValue with sal_Bool as TINYINT

sal_Bool and sal_uInt8 are typedefs for the same underlying type, so any use of
ORowSetValue with sal_Bool instead of bool, apparently intending to treat the
value as a boolean, actually treated it as a TINYINT.  (See e.g. recent
7b0c57b2 "some compilers don't like implicit
bool-to-ORowSetValue conversion".)

Now that there's no way to create a sal_uInt8 ORowSetValue, getUInt8 and the
m_uInt8 union member can probably go away, too.
