[PATCH] ident.c: suppress fprintf 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:
remove unused variables) which removed additional fprintf arguments.

Suppress this warning by using a literal "%s" to print the string
instead of passing the string directly to fprintf.
