Remove fallback definitions of __NR_set_robust_list

[Joseph S. Myers]

In checking for architecture conditionals in common code I found that
nptl/pthreadP.h had fallback definitions of __NR_set_robust_list for
x86 and x86_64.  Since these are defined for both those architectures
in asm/unistd.h in the earliest supported kernel headers version
(2.6.19.1) there is now no need for local definitions in this file and I
propose this patch to remove them.  Tested x86 and x86_64.

	* pthreadP.h [!__NR_set_robust_list] (__NR_set_robust_list): Do
	not define.
