btrfs: update target inode's ctime on unlink
[ Upstream commit 3bc2ac2f8f0b78a13140fc72022771efe0c9b778 ]
Unlink changes the link count on the target inode. POSIX mandates that
the ctime must also change when this occurs.
According to https://pubs.opengroup.org/onlinepubs/9699919799/functions/unlink.html:
"Upon successful completion, unlink() shall mark for update the last data
modification and last file status change timestamps of the parent
directory. Also, if the file's link count is not 0, the last file status
change timestamp of the file shall be marked for update."
