Update linker config location

Linker config location has been changed to /linkerconfig recently to
avoid a chroot issue from art test. To fit this in current test, I just
updated the path from /dev/linkerconfig to /linkerconfig to make ART
test to work with latest code.

Bug: 143458513
Test: m -j passed
