Every []byte to string conversion results in a new allocation. Avoid some by using []byte more. Signed-off-by: Kir Kolyshkin <kolyshkin@gmail.com>
Same as in other places (other parsers here, as well as golang os/user parser and glibc parser all tolerate extra space at BOL and EOL). Signed-off-by: Kir Kolyshkin <kolyshkin@gmail.com>

Lines in /etc/group longer than 64 characters breaks the current implementation of group parser. This is caused by bufio.Scanner buffer limit. Fix by re-using the fix for a similar problem in golang os/user, namely https://go-review.googlesource.com/c/go/+/283601. Add some tests.
