linux: Prevent target file from being trashed when trashing symlink

[0xtimsb]

Closes #22399

Currently, the target file is being trashed when trashing a symlink, and the symlink remains intact. Symlinks are not handled separately yet, so when open is used on a symlink, it gets resolved to the target file.

To fix this, we can get the file descriptor of the symlink by passing libc::O_PATH | libc::O_NOFOLLOW flags to open, and then pass this file descriptor to the existing trash::trash_file from ashpd. However, this would result in an error because ashpd currently does not support trashing symlink files. I have created an issue for it here: bilelmoussaoui/ashpd#255.

For the time being, this PR partially fixes the issue by removing the symlink without trashing so that the target file won't be affected. Once the upstream bug is fixed, we can switch this remove action back to trashing.

Release Notes:

• Fixed target file from being trashed when trashing symlink on Linux.
