debug: Link tst-sprintf-fortify-rdonly-static with -Wl,-z,relro [BZ 33183]

This test requires relro_format be placed in the PT_GNU_RELRO segment.
The ELF linker enables -z relro support by default on all Linux targets
except FRV, HPPA, IA64 and MIPS. On these targets, we need to explicitly
link with -z relro to place relro_format in the PT_GNU_RELRO segment.
