With -funroll-loops the loop body is duplicated, emitting more than one
minu and breaking the scan-assembler-times {\mminu} 1 expectation. Skip
the test when -funroll-loops is present, matching zbb-min-max-04.c.
gcc/testsuite/ChangeLog:
* gcc.target/riscv/zbb-min-max-05.c: Skip under -funroll-loops.

/* Verify that minu/maxu/min/max si3 expansions set SUBREG_PROMOTED,
so that no redundant sext.w is emitted after the min/max. */
