syscalls/core, syscalls/x86: Clean up syscall stub naming convention

Tidy the naming convention for compat syscall subs. Hints which describe
the purpose of the stub go in front and receive a double underscore to
denote that they are generated on-the-fly by the SYSCALL_DEFINEx() macro.

For the generic case, this means (0xffffffff prefix removed):

810f08d0 t kernel_waitid # common C function (see kernel/exit.c)

<inline> __do_sys_waitid # inlined helper doing the actual work
# (takes original parameters as declared)

810f1aa0 T __se_sys_waitid # sign-extending C function calling inlined
# helper (takes parameters of type long;
# casts them to the declared type)

810f1aa0 T sys_waitid # alias to __se_sys_waitid() (taking
# parameters as declared), to be included
# in syscall table

For x86, the naming is as follows:

810efc70 t kernel_waitid # common C function (see kernel/exit.c)

<inline> __do_sys_waitid # inlined helper doing the actual work
# (takes original parameters as declared)

810efd60 t __se_sys_waitid # sign-extending C function calling inlined
# helper (takes parameters of type long;
# casts them to the declared type)

810f1140 T __ia32_sys_waitid # IA32_EMULATION 32-bit-ptregs -> C stub,
# calls __se_sys_waitid(); to be included
# in syscall table

810f1110 T sys_waitid # x86 64-bit-ptregs -> C stub, calls
# __se_sys_waitid(); to be included in
# syscall table

For x86, sys_waitid() will be re-named to __x64_sys_waitid in a follow-up
patch.
