Add Linux Loongarch64 support

[beyond-1234]

Hi, since Go has added support for Loongarch64 since 1.18, so maybe we could have native build for Linux Loongarch64.

You can find a brief introduction about Loongarch here if it's not familiar to you.

notes:

• Linux identifies Loongarch64 as loongarch64 while nodejs treat it as loong64.
• Compiling the executable for loongarch64 requires the latest version golang.org/x/sys package. Details in the commit

Hi,
Loong64 should be supported in Go >= 1.19

Can you please pull in latest master? loongarch support was added in #98 but didn't take into account upgrading sys package.

Compiling the executable for loongarch64 requires the latest version golang.org/x/sys package.

(Note, the CI tests didn't fail to build for loongarch64, so not sure if it's needed)
