build: use long long for __u64 by default

Don't print a verbose configure error in parse-types.h if
<asm/types.h> missing and __[SU]*_TYPEDEF is unset.  This is
always the case for non-Linux builds.

The printf formatting strings all use "%llu" for printing 64-bit
values and this it produces a large number of warnings if __u64
is defined as "unsigned long".  If __U64_TYPEDEF isn't set use
"unsigned long long" for __u64 in ext2-types.h and blkid-types.h
by default instead of using "unsigned long".

Fix a few places where "%d" or "%u" or "%Lu" were used to print a
64-bit value, by converting them to use "%lld" or "%llu" instead.

Fix a few places where "%lu" was used to print .tv_usec, by casting
the variable to "(long)" since .tv_usec is "int" on some systems.
