ident.c: replace fprintf with fputs to suppress compiler warning

Compiling today's pu gave

ident.c: In function 'fmt_ident':
ident.c:206: warning: format not a string literal and no format arguments
    CC list-objects.o
    ...

This warning seems to have appeared first in 18e95f279ec6 (ident.c:

Suppress this warning by using fputs instead of fprintf.
