[Buildroot] [PATCH 1 of 6 v3] legal info: fix saving of host package licenses

[Thomas De Schampheleire]

Due to some tricky make behavior, the license texts of host packages that
did not provide an explicit HOST_FOO_LICENSE_FILES definition was not saved.
The problem is that it is not straightforward to use a variable
defined/updated inside an evaluated block as input to a foreach statement.
If you try to use $(FOO) then only the original value of FOO is used for
foreach, any update inside the block is ignored. However, if you use
$$(FOO), the entire contents of FOO (typically a list of items) is passed
as one item to foreach, thus causing just one iteration instead of several.

From Arnout Vandecapelle's explanation:
Any variable referenced with a single $ inside the inner-generic-package
macro is expanded before the resulting contents are eval'ed. Therefore, it
is not possible to refer to variables defined by the inner-generic-package
macro from within a single-$ function call.

To fix the problem, one should defer the evaluation of the entire block
using double dollar signs.

Additionally, a few empty lines have been added to the legal-info-foo block
for clarity.

v3:
- simplify solution based on Arnout's insight
v2:
- implement a solution for packages that have multiple license files.
- fix accidental mixup of code from another patch

[Buildroot] [PATCH 5 of 6 v3] legal info: cleanup utility functions

[Thomas De Schampheleire]

The legal-info utility functions where defined using two ways
util-foo = command-foo
and
define util-bar # parameter description
	command-bar
endef

This commit changes these functions to use the second form for clarity and
additionally adds parameter descriptions on all functions.
