Make the host_init_verifier init.rc parser follow symlinks.

Bazel's intermediates/inputs are symlinks in its execution root, unlike Soong.

e.g.

$ file $(readlink -f out/bazel/output/execroot/__main__/packages/modules/adb/apex/adbd.rc)
/usr/local/google/home/jingwen/aosp/master-with-phones/packages/modules/adb/apex/adbd.rc:
ASCII text

Test: presubmits
