x86/asm/entry: Rename compat syscall entry points

Rename the following system call entry points:

	ia32_cstar_target       -> entry_SYSCALL_compat
	ia32_syscall            -> entry_INT80_compat

The generic naming scheme for x86 system call entry points is:

	entry_MNEMONIC_qualifier

where 'qualifier' is one of _32, _64 or _compat.
