tracing: Define NR_syscalls for x86 (32)

Add a NR_syscalls #define for x86. This is used in the syscall events
tracing code. Todo: make it dynamic like x86_64.

NR_syscalls is the usual name used to determine the number of syscalls
supported by the current arch. We want to unify the use of this number
across archs that support the syscall tracing. This also prepare to move
some of the arch code to core code in the syscall tracing area.
