Summary:
Minor improvements to a bunch of stuff
- mostly, always log backend stats and time spent analysing, regardless of `-j 1`
- output stats more like they appear in the record
- split `InferAnalyze.main` to be more readable (hopefully)

Different checks contain some ad hoc places that look at this param, but there is no systematic way to suppress this.
The centralized place that is filtering results is `reporting.ml`.
Note that this diff does not remove other usages, because they do more than mere filtering results.

Summary:
The genrule-capture integration with Java relies on a buck config flag `infer.infer_bin=<path to infer>` (see test changes in `DEFS` below).
In a CI environment where the infer binary is checked out under a random directory, this means that the buck genrule is keyed by a random string (the path to infer), and this defeats caching.
Switch to the following contract: the genrule target does not expect a config flag at all. Instead it runs whichever `infer` binary is in the path. To make sure the binary is the same one with the originator, the capture integration runs buck under a modified `PATH` where the originator `infer` is sure to be the first matching entry.
NB cache invalidation is still OK because we rely on `infer.version` buck config flag, which will be hashed into the rulekey.

Summary:
When a file is passed to infer through `--changed-files-index` which is
- an absolute path
- the file does not exist
Then the code fails throwing an exception in the function below while trying to relativise the absolute path.
The behaviour on relative paths is to skip missing files, and does not fail because Infer does not attempt to relativise them.
Swallow the exception and skip the file; and so unify the behaviour across relative and absolute paths.
