[PATCH v1] builtin/checkout.c: replace bit-shift values for macros in call to check_stages

[Edmundo Carmona Antoranz <eantoranz@gmail.com>]

Currently a call to check_stages is using bit-shift values to define what will be used
as the first argument. If the reader doesn't know what the values are from heart, they
have to go dig in cache.h what each value is.

This patch is replacing those values for the macros from cache.h so that it's
clear at first sight what they are (CE_ENTRY_REMOVED, CE_ENTRY_ADDED)
