e2fsprogs_1.42.bb: Fix build fallout for uclibc

e2fsprogs 1.42 onwards uses fallocate() which uclibc
does not implement(yet). In most of places its use
is controlled and it only used when configure detects
fallocate being present but in this one case it missed
to check for fallocate being available so here we
add the check

+We assume that fallocate is supported somehow

+this problem shows up on uclibc systems since
