rs6000: Fix up -D_FORTIFY_SOURCE* with -mabi=ieeelongdouble [PR104380]
The following testcase FAILs when configured with
--with-long-double-format=ieee . Only happens in the -std=c* modes, not the
GNU modes; while the glibc headers have __asm redirects of
vsnprintf and __vsnprinf_chk to __vsnprintfieee128 and
__vsnprintf_chkieee128, the vsnprintf fortification extern inline gnu_inline
always_inline wrapper calls __builtin_vsnprintf_chk and we actually emit
a call to __vsnprinf_chk (i.e. with IBM extended long double) instead of
__vsnprintf_chkieee128.
rs6000_mangle_decl_assembler_name already had cases for *printf and *scanf,
so this just adds another case for *printf_chk. *scanf_chk doesn't exist.
__ prefixing isn't done because *printf_chk already starts with __.

* config/rs6000/rs6000.cc (rs6000_mangle_decl_assembler_name): Also
adjust mangling of __builtin*printf_chk.
* gcc.dg/pr104380.c: New test.
