[Pal/Linux-SGX] Do not overwrite sgx.static_address in manifest

Browse Source 
Previously, the "sgx.static_address" field was overwritten by the
pal-sgx-sign tool in the manifest, even if the manifest author
explicitly specified it as 0 or 1. Sometimes, it is important to keep
sgx.static_address as the manifest author intended. This commit adds a
check to overwrite sgx.static_address only if not specified in manifest.
