[Buildroot] [PATCH 3 of 5 v3] manual package list: add symbol name in table

[Thomas De Schampheleire <patrickdepinguin@gmail.com>]

Particularly in the list of deprecated packages, it is not always clear what
the entry name refers to. For example, for squashfs3 rootfs support, the
string is simply "3.x". Likewise for the flex target binary: "Install tool
in the target".

To clarify the entries, add the actual symbol name (BR2_xxx) in the table.
