openmp: Fix up handling of DECL_OMP_PRIVATIZED_MEMBER for bit-fields [PR95063]
The r11-15 change broke this testcase, as it now asserts type is equal to
the type of the DECL_VALUE_EXPR, but for DECL_OMP_PRIVATIZED_MEMBER artificial
vars mapping to bitfields it wasn't. Fixed by changing the
DECL_OMP_PRIVATIZED_MEMBER var type in that case.
