depends: always configure with --with-pic

We currently do this sporadically. Not only amongst packages, but across
OS's, i.e sometimes it's done for BSDs/Android, and sometimes not.

Configure with `--with-pic` globally instead. I think this generally
makes more sense, and should not have any downsides.

See related discussion in
bitcoin/bitcoin#28846 (comment).

+Where possible, packages are built with Position Independant Code. Either using
+the autotools `--with-pic` flag, or `DCMAKE_POSITION_INDEPENDENT_CODE` with CMake.
