textproc/intltool: fix warnings with perl 5.22

This patch eliminates warnings like this by escaping left brace:
"""
Unescaped left brace in regex is deprecated, passed through in regex;
marked by <-- HERE in m/^(.*)\${ <-- HERE ?([A-Z_]+)}?(.*)$/ at
/usr/local/bin/intltool-update line 1065.
Unescaped left brace in regex is deprecated, passed through in regex;
marked by <-- HERE in m/\${ <-- HERE ?AC_PACKAGE_NAME}?/ at
/usr/local/bin/intltool-update line 1193.
"""

+ 7 more warnings like this when building ports involving intltool (gitg,
gnome-builder etc)

While here replace brackets with braces in download url (porlint warning) and
bump PORTREVISION because of package change.
