Kitty remote binary file loses execute permission on new new connection

[jenuk]

Describe the bug
When using the ssh kitten to connect to a remote server, the permissions for the remote kitty binary are removed, i.e. I can't execute kitty until I readd the execution permission.

To Reproduce
Steps to reproduce the behavior:

[local] $ kitty +kitten ssh cg2

[remote] $ kitty --version
bash: /export/home/jomuelle/.local/share/kitty-ssh-kitten/kitty/bin/kitty: Permission denied

[remote] $ ls -l .local/share/kitty-ssh-kitten/kitty/bin/
total 4
-rw-r--r-- 1 jomuelle CompVis 3840 Mai  4 09:51 kitty

[remote] $ chmod +x .local/share/kitty-ssh-kitten/kitty/bin/kitty 

[remote] $ ls -l .local/share/kitty-ssh-kitten/kitty/bin/
total 4
-rwxr-xr-x 1 jomuelle CompVis 3840 Mai  4 09:51 kitty
