uboot-envtools: set nonshared flag correctly per-subpackage

Currently, uboot-envtools is being built for a (shared) instruction
set (phase2 in buildbots) instead of target-specific (phase1 in builbots).
So the package does not contain the uci-defaults file specific for each
target_subtarget. (Only the fortunate target with coincidentally the same
instruction set and target as the SDK chosen by the buildbot will have the
uci-defaults file.)

This commit sets the nonshared flag correctly in the Makefile so that
uboot-envtools is built for the target-specific (phase 1).

This is done by using the PKGFLAGS variable which is intended for
per-binary flags (instead of PKG_FLAGS which has a global scope), as
stated in some old commits 349e7b635e[1], 2d7eaf2e15[2], 064e7c8f00[3] and
2cb75cd8b9[4].

While at here, use PKG_URL, instead of URL, which is intended for global
scope. As stated in commit e32edf712b[5].
