Scott Little f3ba3ca0f1 build-avoidance: ensure we can write to a copied build environment.
A centos build using build avoidance will fail if the
upstream reference build is read only. The read only
is replicated in the user's build environment, and any
packages that need to be updates (since the reference
build) will fail with reason 'permission denied'

A read only reference build is rare, but can occur to
preserve important reference builds, such as a release build
or the last build prior tothe introduction of a major feature.

Solution is to add a chmod to ensure writability of copied content.

Closes-Bug: 1958156

# Functions related to build avoidance.
#
# Do not call directly. Used by build-pkgs.
#
# Build avoidance downloads rpm, src.rpm and other artifacts of
# build-pkgs for a local reference build. The reference would
# typically be an automated build run atleast daily.
# The MY_WORKSPACE directory for the reference build shall have
# a common root directory, and a leaf directory that is a time stamp
# in a sortable parsable format. Default YYYYMMDDThhmmssZ.
# e.g. /localdisk/loadbuild/jenkins/StarlingX/20180719T113021Z
#
# Other formats can be used by setting the following variables
# in $MY_REPO/local-build-data/build_avoidance_source.
# e.g. to allow format YYYY-MM-DD_hh-mm-ss
# BUILD_AVOIDANCE_DATE_FORMAT="%Y-%m-%d"

# BUILD_AVOIDANCE_DATE_TIME_POSTFIX=""
#
# Note: Must be able to rsync and ssh to the machine that holds the
# reference builds.
#
# In future alternative transfer protocols may be supported.
# Select the alternate protocol by setting the following variables
