* Fix fallback to `cargo-install`: Use the default target
which is guaranteed to work, instead of providing a custom `--target`
from `detect-targets`.
The one from `detect-targets` might report musl even if the `rustc`
reports gnu, since OSes like NixOS could use a custom glibc location
that prevent glibc binaries built for other OSes be run for them.
However, if we are compiling the crate and `rustc` defaults to glibc,
then it should be guaranteed to work.

* Fix `detect-targets` on ubuntu 20.04, glibc 2.31
Fixed#1375 and fixed#1378
glibc 2.31 does not support `--version`, so we need to detect and
fallback to passing an executable linked with that glibc to check if it
is indeed glibc.

* feat `detect-targets`: Improve support of non-std glibc/musl
Fixed#1329
- Refactor: Create `linux::detect_alternative_targets` to reuse code
from other targets
- Run `/lib/ld-linux-{cpu_arch}.so.1 --version` for checking glibc
support instead of running `ldd --version` since it could be non-std
glibc installation and does not provide
`/lib/ld-linux-{cpu_arch}.so.1`
- Check for non-std glibc and add fallback target
`{cpu_arch}-{distro_name}-linux-gnu{abi}`
- Add `{cpu_arch}-{distro_name}-linux-musl{abi}` fallback for musl
libc, specially for Alpine since it has a
`/lib/ld-musl-{cpu_arch}.so.1`
- For unknown libc flavor, check for the target provided before
fallback to musl

Now `detect_targets` would fallback to `x86_64h-apple-darwin` on
`aarch64-apple-darwin`.
It also provides fallback to `x86_64h-apple-darwin` to
`x86_64-apple-darwin` and universal targets.

On Alpine, rustc returns host triple `x86_64-alpine-linux-musl`, so we
have to adopt code from
[`convert_custom_linux_target`](5519aeb5c2/build-common.rs (L1-L13)) to fix this.
* Optimize `get_target_from_rustc`: Avoid frequent String allocation
caused by `Cursor::new(stdout).lines()` which calls `BufRead::lines` and
returns `Lines` iterator, which returns `Item = io::Result<String>`.
