sqlite3.pc missing includedir & libdir

[David Brownlee <abs%absd.org@localhost>]

I'm just playing with building akonadi-1.5.3 against the builtin
sqlite3 from NetBSD-current and it fails
to configure because the shipped /usr/lib/pkgconfig/sqlite3.pc does
not define includedir or libdir.

It would seem to be relatively obvious to add them, but before I do
was there any specific reason they were not included?

Proposed updated file:

# SQLite pkg-config file

includedir=/usr/include
libdir=/usr/lib

Name: SQLite
Description: SQL database engine
Version: 3.7.9
Libs: -lsqlite3
