Adding an executable file to a zip archive with F5 forgets the executable bit

[ilyagr]

1. Open a ZIP archive by pressing Enter on it in the left pane. In my case, the file had VSIX extension (don't think it matters)
2. Find an executable file (in the Unix sense) on the right pane
3. Press F5 and Enter to copy the file into the archive.
4. Observe that the executable bit is not set.

zipinfo confirms that the executable bit is not set. In this example zipinfo file, the last three files were added by MC, the rest were there before.

`console
$ zipinfo test.vsix
Archive: test.vsix
Zip file size: 52810887 bytes, number of entries: 49
(... some files omitted)
-rw-rw-r-- 6.3 unx 3156 b- defN 24-Dec-29 15:49 extension.vsixmanifest
-rw------- 3.0 unx 34599192 bx defN 25-Jan-08 17:52 extension/_dist/superbol-free2
-rw------- 3.0 unx 34599192 bx defN 25-Jan-08 18:08 extension/_dist/superbol-free3
-rw------- 3.0 unx 34599192 bx defN 25-Jan-08 18:08 extension/_dist/superbol-free-linux-x64
49 files, 128163558 bytes uncompressed, 52802923 bytes compressed: 58.8%
`

The expected output would be something like:

`
...
-rw-r--r-- 6.3 unx 2044 bl defN 24-Dec-29 15:29 extension/syntaxes/listfile.tmLanguage.json
-rw-rw-r-- 6.3 unx 3156 b- defN 24-Dec-29 15:49 extension.vsixmanifest
-r-xr-xr-x 6.3 unx 34599192 bx defN 24-Dec-29 15:49 extension/_dist/superbol-free
...
