LD_PRELOAD的妙用，让python支持自己编译的Sqlite

LD_PRELOAD=/usr/local/sqlite/lib/libsqlite3.so.0 python3 -c "import sqlite3; print("sqlite3.sqlite_version");"

会输出

3.27.1

而 python3 -c "import sqlite3; print("sqlite3.sqlite_version");"，输出

3.22.0

xxx@xxx-Alienware-15-R4:/usr/local/sqlite$ LD_PRELOAD=/usr/local/sqlite/lib/libsqlite3.so.0 python3 -c "import sqlite3; print("sqlite3.sqlite_version");"
3.27.1
xxx@xxx-Alienware-15-R4:/usr/local/sqlite$  python3 -c "import sqlite3; print("sqlite3.sqlite_version");"
3.22.0
