Remove `xidel` dependency

[StayPirate]

In the wave of removing as much packages installed form AUR, I need to reconsider the use of xidel.

Currently found in the following aliases:

.config/zsh/alias.d/50-SUSE-IM.alias
67-
68-alias sepkg='f() {
69-# Search packages that build binaries that contains the searched substring (case-insensitive)
70:# Xidel upstream: http://videlibri.sourceforge.net/xidel.html
71-#
72-# Example:
73-#   > sepkg webkit
