domoticz: bump to version 87286ee (beta)

This version includes the patch on execinfo
(commit 775da272719b52bca37b44a40e935a1eb9d10466) so remove
the 0001-add-proper-check-for-detecting-header-execinfo.h.patch file

This version also fixes arc and musl build (ambiguous call to abs and
missing linux/ioctl header):

Due to DOS line endings, it is easier to reference this beta release
than converting git patches.
The stable release should be released in the first week of October.
