Tom Cherry 53940fd2ba Always create /vendor/etc/{passwd,group} 
Previously we only created these if the device set
TARGET_FS_CONFIG_GEN, however there are now other targets that want to
depend on these.  Instead of having those targets conditionally depend
on them, we always create them, defaulting to blank contents (by
reading /dev/null for TARGET_FS_CONFIG_GEN).

Test: builds succeed

# One can override the default android_filesystem_config.h file in one of two ways:
#
# 1. The old way:
# To Build the custom target binary for the host to generate the fs_config
# override files. The executable is hard coded to include the
# $(TARGET_ANDROID_FILESYSTEM_CONFIG_H) file if it exists.
# Expectations:
# device/<vendor>/<device>/android_filesystem_config.h
# fills in struct fs_path_config android_device_dirs[] and
# struct fs_path_config android_device_files[]
# device/<vendor>/<device>/device.mk
# PRODUCT_PACKAGES += fs_config_dirs fs_config_files
# If not specified, check if default one to be found
#
# 2. The new way:
# set TARGET_FS_CONFIG_GEN to contain a list of intermediate format files
# for generating the android_filesystem_config.h file.
#
# More information can be found in the README
