Remove deprecated symlink directories, and remove
services that are not present in our system or vendor.

Common config.fs/$TARGET_FS_CONFIG_GEN AID/fs configuration
file for all chipset inheriting from base.mk.

Since legacy device-specific android_filesystem_config.h and
config.fs do not co-exist, temporarily include config.fs only
if legacy file is absent.  Once all legacy, device-specific
files have been deleted, config.fs can be made unconditional.

On builds where A/B support is enabled the system image acts as the
rootfs. In this case we can no longer create the non-hlos image mount
points at run time as we used to. We now create them as part of the
build itself.

This can be checked by looking for a rild service in system.
If it's missing, then a vendor ril service is being used, in
our case, it is qcrild.

Partitions that use vbmeta_system can be found by looking at
avb flag in fstab from boot ramdisk.

--flags 2 makes the verification function of avb always return a
positive result.

--set_hashtree_disabled_flag builds the vbmeta images with the
HASHTREE_DISABLED bit set and as a result they don't need to manually
disable dm-verity via e.g. 'adb disable-verity'.

The rest of the configuration is taken from

Partition sizes can be found by query-ing sysfs.
For example, for super partition.

> ls -la /dev/block/by-name/super
lrwxrwxrwx 1 root root   16 1970-03-23 06:51 super -> /dev/block/sda17
> cat /proc/partitions | grep sda17
 259        1    8388608 sda17

The size needs to be multiplied by the block size used by
/proc/partitions, which is 1024 bytes.

Logical partitions found inside the physical super partition
can be found by looking for entries with the logical flag in the
fstab inside boot ramdisk.

Can be found by checking the value of ro.vendor.build.security_patch
on stock.
