install: use readlink to resolve symlinks

Browse Source 
The `file(1)` shipped on macOS doesn't resolve symlinks:

    $ echo foo > file
    $ ln -s file link
    $ /usr/bin/file link
    link: ASCII text

Unfortunately the `readlink(1)` on macOS doesn't support the `-f` flag as well,
so we just match against the end of the string.
