File install-info_exitcode.patch of Package texinfo

Author: Adam Majer <amajer@suse.de>
Date: Fri Apr  6 10:59:49 CEST 2018
Bug: bsc#1084997
Summary: revert behaviour change since SLE11/SLE12

For package that tries to remove non-existent info page.

/sbin/install-info --quiet --delete --info-dir=/usr/share/info 
              /usr/share/info/blubber.info.gz ; echo $?
0


in SLE15,

/sbin/install-info --quiet --delete --info-dir=/usr/share/info 
              /usr/share/info/blubber.info.gz ; echo $?

install-info: No such file or directory for 
              /usr/share/info/blubber.info.gz 
1


So, we need to keep return code on failure to be 0 since suse_macros are missing
||: which results in broken packages that worked before to stop working now. This
is affecting upgrade process.
