jadeandGerrit Code Review 9896d309cb Revert "libexpr: Replace regex engine with boost::regex" ...

This reverts commit 447212fa65.

Reason for revert: Regression in eval behaviour bug-compatibility.

Expected behaviour (Nix 2.18.5, macOS and Linux [libstdc++/libc++]):

```
nix-repl> builtins.match "\\.*(.*)" ".keep"
[ "keep" ]

nix-repl> builtins.match "(\\.*)(.*)" ".keep"
[ "." "keep" ]
```

Actual behaviour (boost::regex):

```
nix-repl> builtins.match "\\.*(.*)" ".keep"
[ ".keep" ]

nix-repl> builtins.match "(\\.*)(.*)" ".keep"
[
  "."
  "keep"
]
```
