7z password protected archives

[maxz]

When you try to view encrypted file in 7z archive, MC hangs up.
Only kill MC process helps.
The solution is simple:

diff --git a/src/vfs/extfs/helpers/u7z b/src/vfs/extfs/helpers/u7z
index 91301c3d9..603c976d3 100755
--- a/src/vfs/extfs/helpers/u7z

The same problem with rar and zip encrypted archives but patch exists on the net, but still is not included in MC sources.

Blindly using "-p" is not a good idea. True 7zr binary (not a symlink 7zr -> 7zz like in 7zip package from opensuse 15.6) does not support "-p". So, on a minimal system with only true 7zr available, "$P7ZIP e -so -p- .." always fails
