testsuite: Fix up builtin-clear-padding-3.c for -funsigned-char
As reported on gcc-regression, this test FAILs on aarch64, but my
r15-2090 change didn't change anything on the generated assembly,
just added the forgotten dg-do run directive to the test, so the
test has been failing forever, just we didn't know it.
I can actually reproduce it on x86_64 with -funsigned-char too,
s2.b.a has int type and -1 is stored to it, so we should compare
it against -1 rather than (char) -1; the latter is appropriate for
testing char fields into which we've stored -1.

* c-c++-common/torture/builtin-clear-padding-3.c (main): Compare
s2.b.a against -1 rather than (char) -1.
(cherry picked from commit 958ee138748fae4371e453eb9b357f576abbe83e)
