buf build xyz.tar fails if a file in this archive has an extended attribute #2387
Description
Files created in vscode, and potentially other apps, have an extended attribute. Making a tape archive (.tar) and invoke buf build on such an archive will fail.
Steps to reproduce:
Run the following in the terminal built in to mac (not the one from vscode)
% mkdir dir1 dir2
% mv somewhere/vscode.proto dir1/vscode.proto #### assuming such a file exists and is created by vscode
% echo "message Foo {}" > dir1/vscode.proto
% echo "message Bar {}" > dir2/terminal.proto
% ls -al@ dir1/vscode.proto
-rw-r--r--@ 1 oliversun staff 15 18 Aug 16:46 dir1/vscode.proto

% ls -al@ dir2/terminal.proto
-rw-r--r-- 1 oliversun staff 15 18 Aug 16:46 dir2/terminal.proto
% tar -cvf t1.tar dir1
a dir1
a dir1/vscode.proto
% tar -cvf t2.tar dir2
a dir2
a dir2/terminal.proto
% buf --version
1.22.0
% buf build t2.tar
% buf build t1.tar

Verified on 1.22.0 and 1.26.2-dev (latest main).
