[libc++][AIX] Remove "pragma priority" from locale.cpp

[xingxue]

Summary

The pragma priority guarded for AIX in locale.cpp is no longer useful and is ignored by the current AIX build compilers. This patch removes it from the source.

@xingxue, this is no longer useful because you observed that compiling the file results in no functions being generated to perform non-local initialization?

Right, there are no static constructor functions (__sinit*()) in the resulting locale.cpp.o file.

LGTM

@ldionne, can you approve? The change only affects AIX.

Thanks for cleaning up.
