fix: increase spawnsync buffer

[thomasrockhu-codecov]

Fixes the issue here where running gcov exceeds the buffer size. Also removes unused argument from token.ts

@drazisil-codecov @mitchell-codecov I'm actually not sure why this is. I can repro locally, but removing the line makes all the tests run.

What I've found is adding the { maxBuffer: ... } ish returns undefined for result instead of the object. I have no idea why this is.

[thomasrockhu-codecov]

Ok, so tests are breaking I believe because of the way we are mocking out spawnSync, will try to keep digging

[thomasrockhu-codecov]

I know that's true, because removing the testdouble calls in a test (and changing the values to actual slugs or whatnot) result in passing tests

[mitchell-codecov]

We should evaluate how we're mocking spawnSync in a future PR. It seems unnecessary to have to update each individual mock of the function just to accommodate implementation-level changes in runExternalProgram.

[thomasrockhu-codecov]

@mitchell-codecov agreed, it seems unnecessary
