fs/common: add option to execute custom scripts under fakeroot
Some users have the need to be able to tweak the content of the target rootfs with root-like rights, that is, from inside the fakeroot script. Add a new system option to allow those users to provide a list of scripts, like the post-build and post-image scripts, that will be run from our fakeroot script.

+ This gives users the opportunity to do customisations of the
+ content of the rootfs, which would otherwise require root
+ rigths.
+
+ These scripts are called with the target directory name as
+ first argument. The build will fail on the first scripts that
+ exits with a non-zero exit code.
+
+ Note that Buildroot already provides mechanisms to customise
+ the content of the rootfs:
+
+ - BR2_ROOTFS_STATIC_DEVICE_TABLE
+ to create arbitrary entries statically in /dev
+
+ - BR2_ROOTFS_DEVICE_TABLE
+ to set arbitrary permissions as well as extended attributes
+ (such as capabilities) on files and directories,
+
+ - BR2_ROOTFS_USERS_TABLES:
+ to create arbitrary users and their home directories
+
+ It is highly recommended to use those mechanisms if possible,
+ rather than using custom fakeroot scripts.
