sqlite: use bundled amalgamation on Linux/macOS when pkg-config is unavailable

PythonWillRule · claude · PythonWillRule · commit 1e82558f2df0 · 2026-04-04T00:06:24.000-04:00
When `pkg-config sqlite3` fails, fall back to compiling the bundled
`thirdparty/sqlite/sqlite3.c` directly instead of `-lsqlite3`, which
requires a system development package. Users can obtain the amalgamation
by running `vlib/db/sqlite/install_thirdparty_sqlite.vsh`.
