makefile: fix dangling symlink in uninstall

Fix symbolic links so they are now relative, and also removes a
dangling symlink that was left there with make uninstall
(libhttp_parser.so was left pointing to a non-existant file previously).
Don't hard-code the library name, match the file names of `make install`.
