Expose binutils externally

**What would you like to be added**:

Hi, PR https://github.com/anchore/syft/pull/2585 moved some of the binutils to an internal package and deprecated the existing one. We are relying on some of this to maintain our own subset of binary detection and we will lose this ability in the future. Would it be possible to have that package be available externally?

**Why is this needed**:

To maintain binary detection extensions

Start by reading PR #2585 and comparing the deprecated public binutils package with the package moved internally. Determine which binutils functionality external binary-detection extensions still need and what public API would preserve that use. Done means external consumers can maintain binary detection extensions without relying on the deprecated package.
