focal/linux-lowlatency-hwe-5.15: re-sync local-mangle with hwe-5.15

[Kleber Sacilotto de Souza]

[Impact]
The local-mangle helper script for focal/linux-lowlatency-hwe-5.15 is missing several fix-ups when compared with the script from focal/linux-hwe-5.15.

One of the main issues detected was that CONFIG_AUFS_FS needs to be enabled in all kernels backported to Focal to keep compatibility when users upgrade kernels in the series. This kernel in particular did not have this config option enabled when the backport was created.

[Fix]
Sync the file with the contents from the hwe-5.15 branch, keeping the lowlatency-specific fix-ups.

[Test case]
* CONFIG_AUFS_FS and its related configs should be the same as the hwe-5.15 kernel in Focal.
* The testcase ubuntu_aufs_smoke_test.aufs-smoke-test should be successful.
* All non-lowlatency configs should be the same as hwe-5.15.

[Regression potential]
This is enabling a config options which were disabled before. In case of CONFIG_AUFS_FS, due to being intertwined with overlayfs and shiftfs changes in behavior or regressions could be caused on these two other filesystems.
