[Buildroot] [PATCH 1/1] support/scripts/apply-patches.sh: handle tar and mkdir failures

["Sébastien Szymanski" <sebastien.szymanski@armadeus.com>]

With several archives in a space-separated list of patches, if one archive
cannot be untar (i.e because it is not readable), Buildroot keeps going instead
of aborting. Fix this by checking the tar return code.
While at it, check if the unpack archive directory creation is successful.
