Ruslan Ermilov 886659fe14 - Stop calling libthr alternative as it's now the default
threading library.

- Now that libpthread is a symlink, it's no longer possible
  to link applications with libpthread and have libmap.conf(5)
  select the desired threading library; applications will be
  linked to the default threading library, libkse or libthr.
  Remove an obsolete paragraph.

- Mention that improvements can be seen compared to libkse.
