mozjs-sys-v0.140.10-2: Fix build with crown feature enabled. (#738)

Per #737 this doesn't get detected in either this repository's CI or
Servo's CI. `Heap<T>` is marked `must_root`, and method that return a
`Heap<T>` need to suppress that warning.

Testing: Servo build succeeded with MOZJS_FROM_SOURCE=1, `--use-crown`,
and a local Cargo override.

mozjs-sys-v0.140.8-4: build: Workaround make jobserver bug (#735)

This works around the following bug, where the invocation below fails
with the pipe style and works fine with the new fifo jobserver. Since
there is no sign of cargo going to support fifo jobservers, and single
threaded compilation is horribly slow, we don't pass makeflags on, when
using make 4.4. We use a crude version check, which checks the presence
of the flag - since new make versions are rare, this should be fine for
a while.
If we detect the flag (i.e. make 4.4 or newer), we pass `-j <NUM_JOBS>`
to make instead of inheriting MAKEFLAGS and the jobserver from cargo.
This means we get an upper bound of 2x NUM_JOBS jobs, since the cargo
jobserver and makes jobserver coexist.
We can remove this workaround once cargo [supports fifo style
jobservers](https://github.com/rust-lang/cargo/issues/13483).

Minimum reproducer:

`gmake -j2 --jobserver-style=pipe -f Makefile`

Makefile:
```make
define RECURSE
+$(MAKE) -f sub.mk
endef

all:
	$(RECURSE)
```

sub.mk:

```
all:
	@:
```

Output: `gmake[1]: warning: jobserver unavailable: using -j1. Add '+' to
parent make rule.`

Testing: This is specific to make 4.4, and hence not covered by
automated tests

mozjs-sys-v0.140.8-2: build: Default MOZBUILD_STATE to the target dir (#725)

This moves the mozbuild artifacts from `~/.mozbuild` to inside the cargo
target directory, which means they will be properly cleaned up by `cargo
clean`.

Testing: Covered by `cargo build` still working.
