populate_sdk_base: Fix grep command usage on old hosts
"man grep" on centos:
-R, -r, --recursive
Read all files under each directory, recursively; this is equivalent to the -d recurse option.
"man grep" on a more recent ubuntu system:
-r, --recursive
Read all files under each directory, recursively, following symbolic links only if they are on the command line. This
is equivalent to the -d recurse option.
So we have an issue when the SDK installer (even with
buildtools-tarball) is used on old hosts since it may try and
dereference paths which it should not. This is caused by differences in
the behaviour of grep -r on older systems.
The fix is to wrap this in find so that only real files are found (as
elsewhere in the script.
