Subject: [PATCH v2] x86: entry: Remove _TIF_SINGLESTEP define leftover

After commit 6342adcaa683 ("entry: Ensure trap after single-step on
system call return") a _TIF_SINGLESTEP define is obsolete for arch/x86.

So, remove the leftover in arch/x86/include/asm/thread_info.h file.

Fixes: 6342adcaa683 ("entry: Ensure trap after single-step on system call return")
