During a package build we call prepare_buildenv in multiple stages of
the process. For debug packages, one of the hooks is buildenv_debugflags
which populates the debug flags to the according variables.
The issue is that the behavior of the current implementation of
buildenv_debugflags is not idempotent, so consecutive calls will append
the same flags again. In certain cases this isn't an issue, however
for context aware build frontends like cargo any change of the build
inputs leads to a fresh build. This means that any invocation of such
a build ecosystem inside the package() function will trigger a full
rebuild, which is not desired.
To fix this issue, this commit makes buildenv_debugflags idempotent
by only appending flags once to the target variables.

In some cases packages are built outside of a directory which contains
pkgname-pkgver, this results in source listing in debug packages having
a conflicting path like `/usr/src/debug/build/` which is not ideal.
This patch ensures we always include the pkgbase to ensure the paths are
unique.

>From gcc(1):
-ffile-prefix-map=old=new
[...] Specifying this option is equivalent to specifying all the
individual -f*-prefix-map options. This can be used to make reproducible
builds that are location independent.
Specifically, this additionally enables -fmacro-prefix-map=, which causes
prefix mapping to be applied to expansions of __FILE__ and similar macros.
Without this option, if source files are compiled by passing the
absolute file path to the compiler (as done by e.g. cmake), any
expansions of __FILE__ (e.g. from uses of assert()) will contain
$srcdir.

The rust language supports $RUSTFLAGS to be used automatically in all
rustc invocations. Allow setting this in makepkg.conf (e.g. for
optimization or debuginfo support), and teach debug+strip to pass the
rustc command line argument necessary to rewrite source file paths in
the debugging symbols.

This opens the door for third parties to provide libmakepkg
extentions for the purpose of altering the build environment.
