Fix installation of shared library symlinks

Use relative symlinks that are independent of installation prefix.

Drop superfluous .so.MAJOR.MINOR symlink, which is and should never
be needed in practice. The purpose of shared library symlinks is to
provide libraries for compile-time linking (.so) and for run-time
linking using the SONAME (.so.MAJOR).
