git: use DESTDIR=$D instead prefixing all variables by $D
* with git-native and rm_work enabled I've noticed git fetcher errors like:
warning: templates not found /OE/shr-core/tmp/work/x86_64-linux/git-native-1.7.3.4-r0/image/OE/shr-core/tmp/sysroots/x86_64-linux/usr/share/git-core/templates
fatal: Unable to find remote helper for 'http'
for every recipe using http:// for git repo
* after this change template_dir points to
/OE/shr-core/tmp/sysroots/x86_64-linux/usr/share/git-core/templates
without that workdir prefix
* haven't tested target recipe, but I guess it needs different fix or
maybe it worked before and gets broken by this change
