girnode: Explicitly lose precision on parsed float values 
When building a typelib, the values of constants need to be converted
from a string format (from the GIR) to a binary format. This is
currently done, for all numeric types, using `g_ascii_strto*()`
functions, but with minimal validation. String values which are not
representable as binary numbers are either silently truncated or
clamped.

`-Wfloat-conversion` has flagged that this happens for floats – a
double-precision return from `g_ascii_strtod()` is implicitly cast down
to a float.

While we should ideally have some better error handling so that
conversion to a typelib fails if a constant is not representable in the
typelib, this is a problem for *all* numeric types and not just `float`,
so add an explicit cast to ignore the error for now.

In practice there probably isn’t a problem for any numeric types here,
as there should be validation of the string value when the GIR is
generated anyway.
