IMFS: Fix truncate according to POSIX
ftruncate() and open() with O_TRUNC shall upon successful completion
mark for update the st_ctime and st_mtime fields of the file.
truncate() shall upon successful completion, if the file size is
changed, mark for update the st_ctime and st_mtime fields of the file.
The POSIX standard "The Open Group Base Specifications Issue 7", IEEE
Std 1003.1, 2013 Edition says nothing about the behaviour of truncate()
if the file size remains unchanged.
Future directions of the standard may mandate the behaviour specified in
ftruncate():
