[test] [llvm-objcopy] Fix broken test case

[abrachet]

Summary

The test case added in D62718 did not work unless the user was root because write bits were not set for the output file. This change uses only permissions with user write (0200) to ensure tests pass regardless of the users permissions.

You can join the two lines:

ls -l %t2 | cut -f 1 -d ' ' | cmp - %t.0600

 ## This tests that the umask is respected when
 ## assigning permissions of output files.
 
 ## Windows has no umask so this test makes no sense, nor would
 ## it work because there is no umask(1) in a Windows environment
