pseudo: Ensure we use our own libsqlite

pseudo-native is special in that bitbake ends up executing it from the
sysroot-components directory before we have any workdirs for the bitbake
fakeroot worker. Since we switched to dynamically linking sqlite, it
means sqlite from the host system may be found, we really want the version
in sysroot-components. Trying to run tasks to create some special environment
for pseudo is hard and error prone. The simplest fix is to add an RPATH to
the binary so that it can correctly find the sqlite we want.

Unfortunately passing $ORIGIN into make doesn't work so well with shell
quoting so we have to fix that during do_install.
