DDS: Fix warning in qfloat16 and test failure on PowerPC

Fixes the following warning:
```
/home/daniel/kimageformats/src/imageformats/dds.cpp: In function ‘qfloat16 readFloat16(QDataStream&)’:
/home/daniel/kimageformats/src/imageformats/dds.cpp:1037:11: warning: ‘void* memcpy(void*, const void*, size_t)’ copying an object of non-trivial type ‘class qfloat16’ from an array of ‘quint16’ {aka ‘short unsigned int’} [-Wclass-memaccess]

```

Should also fixes the following failed tests under PowerPC (32-bits):
```
INFO : rgba16dx10.dds: converting rgba16dx10.dds from RGBA16FPx4 to ARGB32
FAIL : rgba16dx10.dds: differs from rgba16dx10.png
       expected data written to rgba16dx10.dds-expected.data
       actual data written to rgba16dx10.dds-actual.data
```
```
