toolchain helpers: introduce function relpath_prefix

Browse Source 
The helper function copy_toolchain_sysroot has some logic to transform a
path into a number of '../' components based on the depth of that path.

As this same logic will be needed in another place in a subsequent patch,
extract it into a separate helper relpath_prefix.

# Given a path, determine the relative prefix (../) needed to return to the

# relpath_prefix(lib32) = ""
# relpath_prefix(lib32/octeon2) = "../"
# relpath_prefix(lib32/octeon2/) = "../../"
#
# $1: input path
