zdtm: moved lib/atomic.h to lib/arch/x86/include/asm/atomic.h

The file lib/atomic.h is the only machine-dependent file in the test suite
that breaks compilation of the test static/session01 on ARM.

The file is moved into a separate directory and the build system is modified
accordingly to prevent this.
