[PATCH] contrib/scalar: fix 'all' target in Makefile

[Victoria Dye via GitGitGadget]

From: Victoria Dye <vdye@github.com>

Add extra ':' to second 'all' target definition to allow 'scalar' to build.
Without this fix, the 'all:' and 'all::' targets together cause a build
failure when 'scalar' build is enabled with 'INCLUDE_SCALAR':

    Makefile:14: *** target file `all' has both : and :: entries.  Stop.

    contrib/scalar: fix 'all' target in Makefile
    
    This patch fixes an issue introduced in a36b575aab (scalar Makefile: use
    "The default target of..." pattern, 2022-03-03) in which an 'all::'
    target was added without converting the existing 'all:' (single-colon)
    target into an 'all::' (double-colon) target. This causes a build error,
    but only when compiling with 'INCLUDE_SCALAR' enabled. As a result, I
    only just found it when building 'scalar' on the 'microsoft/git' fork.
    
    Although 'INCLUDE_SCALAR' isn't enabled by default, we should fix the
    build error for anyone that may intentionally build with it. If
    possible, it would be nice to have this merged before the final v2.36.0
    so that users don't run into the error in the next release.

Thanks for the fix, and sorry.

I missed this because I build and install scalar locally with a patch on
top[1] to integrate it into the main Makefile, so I wasn't running this
part, even if I was building, testing and installing it as part of my
local build.
