tests: cover OpenSSL backend, exclude system-failure paths, tighten filter

Three coverage-related changes:

- New `test_backend_openssl` exercises every failure path in
  `src/openssl.c` (lines 18, 24, 27, and the parallel
  `EVP_DecryptFinal_ex` goto). Each test wraps one EVP call to fail
  while earlier ones succeed, then asserts
  `dbc_decrypt_aes_128_cbc` returns -1. Like `test_backend_win32`,
  this target is gated on `NOT APPLE` (ld64 lacks `--wrap`) and on
  `find_package(OpenSSL)` succeeding (so it skips the Windows
  default-backend build but runs on Linux and Windows-MSYS2).
- The lcov `--remove` patterns on the Linux/macOS native job now
  also exclude `*/test_*` and the absolute-path
  `${{ github.workspace }}/tests/*` so the coverage report omits
  test sources unconditionally.
- `src/api.c` gets `LCOV_EXCL_START`/`LCOV_EXCL_STOP` brackets
  around the seven cleanup-on-allocation-failure / cleanup-on-stdio-
  failure branches that can't realistically be exercised without
  mocking malloc/fseek/ftell/fread. These are obvious system-failure
  paths that pad the uncovered-line count without representing real
  coverage gaps.
