Update linkerconfig to target out directory

Browse source 
Current linkerconfig targets for specific output file. However,
linkerconfig will generate more than 1 file based on APEX modules, so it
should take argument for target directory rather than target file. This
change updates linkerconfig's argument to point output directory.

Bug: 146993126
Test: m -j passed & Cuttlefish succeeded to boot
