mesa: Make glGetInteger64v convert float/doubles to 32-bit integers.

According to the GL 4.4 core specification, section 2.2.2 ("Data
Conversions For State Query Commands"):

"If a command returning integer data is called, such as GetIntegerv or
 GetInteger64v, a boolean value of TRUE or FALSE is interpreted as one
 or zero, respectively. A floating-point value is rounded to the nearest
 integer, unless the value is an RGBA color component, a DepthRange
 value, or a depth buffer clear value. In these cases, the query command
 converts the floating-point value to an integer according to the INT
 entry of table 18.2; a value not in [−1, 1] converts to an undefined
 value."

The INT entry of table 18.2 shows that b = 32, meaning the expectation
is to convert it to a 32-bit integer value.

dEQP-GLES3.functional.state_query.floats.color_clear_value_getinteger64
