[LTP] [PATCH 1/1] checkpatch: Pass git root

[Petr Vorel]

checkpatch.pl --strict parameter added in 1908cd77c2 expects --root
parameter when running with --no-tree due searching in $root/include/
directory.

This fixes warning on files with CAMELCASE check (corner case):

    $ cd testcases/kernel/syscalls/statx; make check-statx02
    CHECK testcases/kernel/syscalls/statx/statx02.c
    Use of uninitialized value $root in concatenation (.) or string at
    scripts/checkpatch.pl line 1213.
    find: ‘/include’: No such file or directory
    statx02.c:52: CHECK: Avoid CamelCase: <PRIu64>
    ...

Fixes: 1908cd77c2 ("make check: b4: Use --strict when run checkpatch.pl")

NOTE: I'll verify the usage with kernel checkpatch.pl maintainers.

Kind regards,
Petr
