jq: Avoid SIGSEGVs when using date builtins

Apply patch written by <soda> and shared with upstream as part of
<https://github.com/stedolan/jq/pull/1458> in order to fix crashes of jq when
using date builtin functions.

Also add a SUBST class intended to avoid invoking git as part of pre-configure
phase when invoking autoreconf.

While here take the MAINTAINERship and reformat a bit the Makefile
(NFCI).

Thanks a lot to <soda>, Takehiko NOZAKI and <nonaka> for investigating
the issue, writing the patches, sharing them with upstream and as
part of PR pkg/52460!
