Enable installation of go on ppc64/ppc64le systems

[kishen-v]

Description:
Enable setup-go on ppc64le systems. I do see there is a block of code to related to this, which is commented.

setup-go/src/system.ts

Lines 27 to 29 in 41dfa10

	// case 'ppc':
	// arch = 'ppc64';
	// break;

However, with NodeJS not having the capability to determine the endianness of the host using the generic os.arch() call, it is imperative to have os.endianness() differentiate and pick bundles for installation on ppc64/ppc64le systems.

I am using a self-hosted ppc64le system, on which the issue was observed.

Justification:
This change can help to install go on ppc64/ppc64le systems using setup-go, which are added as self-hosted runners.
