kbuild: Fix build target deb-pkg: ln: failed to create hard link

Browse Source 
[ Upstream commit c61566538968ffb040acc411246fd7ad38c7e8c9 ]

The make deb-pkg target calls debian-orig which attempts to either
hard link the source .tar to the build-output location or copy the
source .tar to the build-output location.  The test to determine
whether to ln or cp is incorrectly expanded by Make and consequently
always attempts to ln the source .tar.  This fix corrects the escaping
of '$' so that the test is expanded by the shell rather than by Make
and appropriately selects between ln and cp.
