David Sterba 405e36d53c btrfs-progs: convert: check for extra timespec support in e2fsprogs
In 5.10 the convert gained support for extended inode time precision,
but this is not available on older distros and breaks build. Add a
configure-time check for the EXT4_EPOCH_MASK macro and add a stub in
case it's not detected.

This means that the 64bit timestamps will not be transferred from the
original filesystem in such environment, at least a warning is printed.

Issue: #344
