Use ro.vndk.lite to determine the ld.config.txt

This commit adds an extra check on `ro.vndk.lite`.  If `ro.vndk.lite` is
true, the linker will pick `/system/etc/ld.config.vndk_lite.txt`.

The purpose of this change is to distinguish:

1. Master-GSI + Master-VENDOR (w/o BOARD_VNDK_VERSION for upgrading devices)
2. Master-GSI + O-MR1-VENDOR (w/ BOARD_VNDK_VERSION)
