x86/asm/entry/64/compat: Rename ia32entry.S -> entry_64_compat.S

So we now have the following system entry code related
files, which define the following system call instruction
and other entry paths:

   entry_32.S            # 32-bit binaries on 32-bit kernels
   entry_64.S            # 64-bit binaries on 64-bit kernels
   entry_64_compat.S	 # 32-bit binaries on 64-bit kernels
