[Buildroot] [PATCH] intltool: add patch to fix compatibility with Perl 5.26

[Jörg Krause]

When Perl 5.26 is installed on the host, building some packages like
avahi fail, because of intltool-update:

```
Unescaped left brace in regex is illegal here in regex; marked by <-- HERE in m/^(.*)\${ <-- HERE ?([A-Z_]+)}?(.*)$/ at $BUILDROOT/host/usr/bin/intltool-update line 1065.
```

Apparently, this has been a warning before Perl 5.26, but now it is an
error.

Applied to master, thanks.

FWIW, the bug was already reported upstream at
https://bugs.launchpad.net/intltool/+bug/1490906.

Peter: this is a build fix, we perhaps want it in the LTS branches?

Best regards,

Thomas

Yes, I think so. Committed to 2017.02.x and 2017.05.x, thanks!
