Mark Mentovai 22e8c33b21 linux: Provide PTRACE_GET_THREAD_AREA for 32-bit x86 with glibc
glibc’s own <sys/ptrace.h> should provide this but doesn’t. See
https://sourceware.org/bugzilla/show_bug.cgi?id=22433.

The copy in compat provided it when targeting x86-64 and using glibc.
util/linux/ptracer.cc uses it when targeting both 32-bit x86 and x86-64,
so the compat definition must be made to apply to 32-bit x86 too.

This also provides a #define using the same name as the constant, which
is what glibc’s <sys/ptrace.h> does for other constants.
