File mode discrepancies between tarball and ncurses-snapshots git repository

[Sven Joachim]

There are four scripts which are executable in the ncurses-snapshots git
repository[1], but not in the tarballs at invisible-island.net.

I consulted the Debian git repository where I import the weekly
tarballs, and apparently the four scripts lost their executable bits in
the 20210619 patchlevel.  Obviously ncurses builds fine anyway, but it
looks more correct to make these files executable.

Have a nice Sunday,
Sven
