Convert in-tree sysent targets to use new makesyscalls.lua flua is bootstrapped as part of the build for those on older versions/revisions that don't yet have flua installed. Once upgraded past r354833, "make sysent" will again naturally work as expected.

sysent: Reduce duplication and improve readability. Use the power of variable to avoid spelling out source and generated files too many times. The previous Makefiles were hard to read, hard to edit, and badly formatted.

Set .ORDER for makesyscalls generated files When either makesyscalls.lua or syscalls.master changes, all of the ${GENERATED} targets are now out-of-date. With make jobs > 1, this means we will run the makesyscalls script in parallel for the same ABI, generating the same set of output files. Prior to r356603 , there is a large window for interlacing output for some of the generated files that we were generating in-place rather than staging in a temp dir. After that, we still should't need to run the script more than once per-ABI as the first invocation should update all of them. Add .ORDER to do so cleanly.
