[COMMITTED] ARM: Fix builtin-bswap-1.c test [PR113915]

[Wilco Dijkstra]

On Thumb-2 the use of CBZ blocks conditional execution, so change the
test to compare with a non-zero value.

gcc/testsuite/ChangeLog:
        PR target/113915
        * gcc.target/arm/builtin-bswap.x: Fix test to avoid emitting CBZ.
