s390/clean-up: use CFI_* macros in entry.S

Commit f19fbd5ed642 ("s390: introduce execute-trampolines for
branches") introduces .cfi_* assembler directives.  Instead of
using the directives directly, use the macros from asm/dwarf.h.
This also ensures that the dwarf debug information are created
in the .debug_frame section.
