package/libapparmor: remove stale reference to patch 0001

The AUTORECONF variable was introduced in commit [1] with reference to
the patches that modified the m4 and Makefile.am files.

The commit [2] removed the last such patch but left the reference to the
patch and the AUTORECONF variable.

Later, commit [3] updated the mirror to the gitlab URL that no longer
bundle a pre-generated `configure` file, making the execution of
AUTORECONF necessary anyway.

This patch removes the obsolete reference to the patch 0001 removed in
[2] to avoid ambiguity with the new patch 0001 introduced in commit [4].

[1] 01a82c1401 package/libapparmor: enable python bindings
[2] 27cd0b5033 package/apparmor: bump to version 3.0.4
[3] 5649202ddc package/libapparmor: bump to version 3.1.7
[4] 2640f5dcd0 package/libapparmor: fix build w/ musl
