fstests: fix compilation error in splice2pipe on old (<C99) compilers
Compilation fails on system with compiler which uses older C dialect
(e.g. RHEL7; gcc with gnu90) with:
splice2pipe.c: In function 'prepare_pipe':
splice2pipe.c:54:2: error: 'for' loop initial declarations are only allowed in C99 mode
for (unsigned r = pipe_size; r > 0;) {
Fix it by declaring 'r' outside of the loop.
