Bug 297345: databases/py-sqlite3: Cannot load extensions
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=297345



--- Description ---
I was playing with this port and I found it doesn't allow loading sqlite
extension .so files.  This is easily verifiable even without an extension by
the following snippet throwing exceptions:

    import sqlite3
    conn = sqlite3.connect(":memory:")
    conn.enable_load_extension(True)

Looking at the port I found that nothing was setting the C macro
PY_SQLITE_ENABLE_LOAD_EXTENSION.  This is normally set by the python configure
script, which gets bypassed for this port.

I was able to fix it in my own use with the attached patch.
