fix mksh_sdirsep() and simplify mksh_vdirsep() on OS/2 

mksh_sdirsep() returned a position of a more far directory separator
if '/' and '\' were mixed.

And mksh_sdirsep() returned a position of ':' even if a directory
separator follows. For example, in case of 'x:/', the position of
'/' should be returned not ':'.

mksh_vdirsep() were simplified with mksh_sdirsep().
