e2fsprogs: the max length of debugfs argument is too short
The max length of debugfs argument is 256 which is too short, the
arguments are two paths, the PATH_MAX is 4096 according to
/usr/include/linux/limits.h, so use BUFSIZ (which is 8192 on Linux
systems), that's also what the ss library uses.
This patch has been reviewed by the linux-ext4 mailing list, but isn't
merged atm.
