package/jq: bump to git version a97638713ad3 (still 1.6-based)

jq 1.6 has a severe performance regression compared to 1.5. The problem is
reported [1] and fixed [2] upstream, but there are different commits and
later subsequent fixes on top of them that make it cumbersome to patch
specifically.

Instead, bump to a recent git version.
