[fuchsia][eigen] fix neon vectorization of pmul(Packet1cd,Packet1cd)

The latest calng roll for fuchsia is failing from

```
error: argument value 1 is outside the valid range [0, 0]

v2 = vdupq_lane_f64(vget_high_f64(a.v), 1);
```

`vdupq_lane_f64` eventually calls `__builtin_neon_splatq_lane_v` whose
second argument can only have a value of 0.

The upstream fix for this
(https://gitlab.com/libeigen/eigen/-/commit/7ad1aaec1db2dbf1abfc19a5bb62626653fa48fb)
seemed to just change this argument from 1 to 0.
