selftests/ftrace: Drop invalid top-level local in test_ownership

test_ownership.tc is sourced by ftracetest under /bin/sh.

The script currently declares mount_point with local at file scope,
which makes /bin/sh abort with "local: not in a function" before the
test can reach the eventfs ownership checks.

Replace the top-level local declaration with a normal shell variable so
kernels that support the gid= tracefs mount option can run the test at
all.
