Ensure path seperator between dirname and filename

Previously new-hbmenu assumed that dirname always ended with a '/'.
This used to be the case with devkitARM, however this is not portable, and
on for example, linux the path does not end in a '/'.

Recently devkitARM was changed to ensure that the path never ends in '/'.
