style: restore original test_php_lsp.c formatting

The previous commit's clang-format pass reformatted the whole file
(tests are not in the lint-enforced LINT_SRCS set, so the committed
file was never format-clean under the local formatter). Restore the
original formatting; the branch's net diff against main is now exactly
the two new regression guards.
