strsignal.3: SYNOPSIS: Add missing 'const' 

glibc uses 'const' in sigdescr_np(), sigabbrev_np().
Let's use it here too.

.../glibc$ grep_glibc_prototype sigdescr_np
string/string.h:469:
extern const char *sigdescr_np (int __sig) __THROW;
.../glibc$ grep_glibc_prototype sigabbrev_np
string/string.h:466:
extern const char *sigabbrev_np (int __sig) __THROW;
.../glibc$
