Subject: [PATCH] selftests: livepatch: set LC_ALL=C to fix locale-dependent test failure

When executing the command
"make -C tools/testing/selftests TARGETS=livepatch run_tests",
the following error message was reported.

TEST: livepatch interaction with ftrace_enabled sysctl ... not ok
...
livepatch: sysctlo
: setting key "kernel.ftrace_enabled": Device or resource busy
livepatch: sysctl: setting key "kernel.ftrace_enabled": 设备或资源忙
...
ERROR: livepatch kselftest(s) failed
not ok 5 selftests: livepatch: test-ftrace.sh # exit=1

To fix it, set LC_ALL=C.
