MF Symlinks are regular files containing content in a specified format.
The function couldbe_mf_symlink() checks the mode for a set S_IFREG bit
as a test to confirm that it is a regular file. This bit is also set for
other filetypes and simply checking for this bit being set may return
false positives.
We ensure that we are actually checking for a regular file by using the
S_ISREG macro to test instead.
