roll: pigweed, pw_toolchain: pw_spi_linux: Remove linkage specification from cli main

According to the C++ standard, the main function shall not be declared
with a linkage-specification. An upcoming Crosstool release includes
[20-1706 [Clang] Strengthen checks for `main`  to meet
`[basic.start.main]p3`’s requirements (#101853)](http://go/compilers/37ec6e5f12afe4a37872bf28f280423696f39019),
which will lead to breakages when compiling `extern "C" int main...`.

This CL removes the linkage specification from pw_spi_linux_cli's main
function and moves the main function to the global namespace.
