[LTP] [PATCH v2 1/1] editorconfig: add consistent formatting rules for LTP

[Jan Polensky]

Introduce .editorconfig to keep indentation and whitespace consistent across
editors, preventing accidental reformatting and noisy diffs.

Changes since v1 (thanks Petr):
- License identifier: GPL-2.0 -> GPL-2.0-or-later
- Drop awk
- Treat Python/Perl special files
- indent_size=4 for *.{c,h,S,sh} and ver_linux
- Fix indent_size for .rst/.md to 4
