Provide `aarch64` build of `tsc-dyn.so` for AArch64 Linux

[l2dy]

As of 0.18.0, only x86_64 binaries are provided for Linux.

This is similar to #88, but for Linux.

My temporatory solution:

• cd to ~/.emacs.d/elpa/tsc-20220212.1632
• build via cargo build (need rust toolchain)
• copy the lib file: cp target/debug/libtsc_dyn.so ./tsc-dyn.so
