This also takes the chance to move forward the job to Linux v6.19-rc7,
thus the previous workaround is not needed anymore.

link modifier `export-symbols`: export all global symbols from selected uptream c static libraries

In order to be able to export symbols from a specified upstream C static library, I redesigned a solution that, compared to a previous PR rust-lang#150335 I submitted, will not have any extra symbols leaking out.

The following points should be noted:
 - This attribute will select and import the `Global` symbols of the first matching library it finds.
 - Developers should ensure that there are no libraries with the same name.
 - This modifier is only compatible with `static` linking kind
 - By default, upstream C static libraries will not export their `Global` symbols regardless of whether `LTO` optimization is enabled. However, after enabling this attribute, if the upstream C static library has `LTO` optimization enabled, the compiler will issue an error to inform the developer that the linked C library is invalid.

The test code is the same as the PR rust-lang#150335.
Here are the results:
1. `cargo +include-libs rustc --release -- -L. -lstatic:+export-symbols=c_add`
(or you can use `#[link(name = "c_add", kind= "static", modifier = "+export-symbols")]` in the file)
