mesa: guard better when building with sse4.1 optimisations
When the compiler is not capable/does not accept -msse4.1 while the target
has the instruction set we'll blow up as _mesa_streaming_load_memcpy is
going to be undefined.
To make sure that never happens, wrap the runtime cpu check+caller in an
ifdef thus do not compile that hunk of the code.
Fix the android build by enabling the optimisation and adding the define
where applicable.
v2: autoconf conditionals end with "fi" rather than endif.
v3: Wrap the definition and call to intel_miptree_{un,}map_movntdqa in
if defined(USE_SSE41). Spotted by Matt.
