postgres_storage: Changed type in unsafe block to be able to compile on arm64 architecture

[nebucaz]

@WadeBarnes thanks for the hint: Replaced *const i8 with libc::c_char in unsafe {} blocks in file lib.rs to be able to compile on linux/arm64 architecture. Now compiles on Ubuntu 20.04 aarch64 and MacOS 12.0.1 (Apple M1, arm64/v8). Rust Version: 1.56.0

unsafe { *tags_json_ptr = record.tags.as_ptr() as *const libc::c_char; }

Deprecation Warnings Changed deprecated use of err.description() to silence warnings warning: use of deprecated item std::error::Error::description: use the Display impl or to_string() in src/common.rs, src/wallet.rs, src/crypto.rs
