collector: beautify warning when include\exclude filters wrong

[klensy]

Fixes #1886

Instead of:

$ ./target/debug/collector.exe binary_stats +nightly-x86_64-pc-windows-msvc \
    --rustc2 +nightly-x86_64-pc-windows-msvc --include "helloworldasd" --profile Debug --backend Llvm
collector error: Warning: one or more unused --include entries: ["helloworldasd"]

will print:

$ ./target/debug/collector.exe binary_stats +nightly-x86_64-pc-windows-msvc \
    --rustc2 +nightly-x86_64-pc-windows-msvc --include "helloworldasd" --profile Debug --backend Llvm
collector error: Warning: one or more unused --include entries: ["helloworldasd"] found.
Expected zero or more entries or substrings from list: ["await-call-tree", "bitmaps-3.1.0", "cargo-0.60.0", "clap-3.1.6", "coercions", "cranelift-codegen-0.82.1", "ctfe-stress-5", "deep-vector", "deeply-nested-multi", "derive", "diesel-1.4.8", "encoding", "exa-0.10.1", "externs", "futures", "helloworld", "helloworld-tiny", "html5ever", "html5ever-0.26.0", "hyper-0.14.18", "image-0.24.1", "inflate", "issue-46449", "issue-58319", "issue-88862", "libc-0.2.124", "many-assoc-items", "match-stress", "piston-image", "projection-caching", "regex", "regex-1.5.5", "regression-31157", "ripgrep-13.0.0", "ripgrep-13.0.0-tiny", "serde-1.0.136", "serde_derive-1.0.136", "stm32f4-0.14.0", "style-servo", "syn", "syn-1.0.89", "token-stream-stress", "tokio-webpush-simple", "tt-muncher", "tuple-stress", "typenum-1.17.0", "ucd", "unicode-normalization-0.1.19", "unify-linearly", "unused-warnings", "webrender-2022", "wf-projection-stress-65510", "wg-grammar"].

First commit reworks include\exclude\exclude_suffix args to be parsed by clap as Vec instead of Option and later manually parsed, second one adds existing bench list to error output.

One nit, otherwise LGTM.
