small testsuite framework fix

[Manuel López-Ibáñez]

:ADDPATCH testsuite:

This patch fixes the testsuite test-framework: the "no effect" warning
is not enabled by Wextra but by Wunused-value. Also, the command in
the README was not accurate.

Bootstrapped, regression tested and framework tested.

Cheers,

Manuel.

  * gcc.test-framework/README: Correct command.
  * gcc.test-framework/dg-outexistsnot-exp-P.c: Replace -W with -Wunused-value.
  * gcc.test-framework/dg-outexists-exp-F.c: Likewise.
