kunit: test: Make filter strings in executor_test writable

KUnit's attribute filtering feature needs the filter strings passed in
to be writable, as it modifies them in-place during parsing. This works
for the filters passed on the kernel command line, but the string
literals used in the executor tests are at least theoretically read-only
(though they work on x86_64 for some reason). s390 wasn't fooled, and
crashed when these tests were run.

Use a 'char[]' instead, (and make an explicit variable for the current
filter in parse_filter_attr_test), which will store the string in a
writable segment.
