Kernel: Fix `write`s to `ProcFS` (#6879)
When using `sysctl` you can enable/disable values by writing to the
ProcFS. Some drift must have occured where writing was failing due to
a missing `set_mtime` call. Whenever one `write`'s a file the modified
time (mtime) will be updated so we need to implement this interface in
ProcFS.
