Buildroot commit dcee99507c bumped icu
from version 73-2 to 77-1.
Upstream raised the minimum C++ requirement to C++17 in version 75-1:
https://github.com/unicode-org/icu/releases/tag/release-75-1
https://icu.unicode.org/download/75
"C++ code now requires C++17 [...]"
Consequently, this commit switches the minimum gcc version needed by
package/icu to 7, and propagates this to icu's reverse dependencies.
No autobuilder errors were recorded since we don't test toolchains as
old as gcc 6.x
