sstate/path.py: Add copyhardlinktree() function and use for performance optimisation
Add a function which copys a tree as a set of hardlinks to the original files, then use this in sstate to reduce some of the overhead of sstate package creation since the file isn't actually copied. (From OE-Core rev: 8e373e69acac853213a62afb8bbdf0adc0c5045a) Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
