buildbot: Avoid warnings from linkerconfig
linkerconfig complains if it can't find /system_etc or /product
partition, or if it fails to open /apex/<name>/apex_manifest.pb.
To avoid those warnings when running buildbot-build.sh, a temporary root
for linkerconfig is prepared with /system_etc and /product partitions
and also /apex directories with only relevant APEXes.

Test: lunch aosp_arm64-userdebug

# no warnings from linkerconfig
