core: search WEECHAT_EXTRA_LIBDIR for plugins (closes #971, issue #979)

Browse Source 
In addition to searching the statically configured WEECHAT_LIBDIR
(weechat's installation directory) for plugins, search the path
given in the environment variable WEECHAT_EXTRA_LIBDIR. This makes
departing from the FHS standard while keeping the plugins packaged
separately easier. This change was made specifically with the Nix
package manager in mind, but can easily be used by others.
