We run from a non-interactive shell, so the exec which is inevitably
called will replace the current process and 'die' will never run under
any circumstances.

This also fixes a bug with the su fallback which would cause multiple
arguments to be concatenated without any whitespace between them.

Fixes a breakage introduced in 6db31cc1 which leads to errors
being masked from makechrootpkg.

In collaborative builder machine, these scripts are often allowed to become root
via sudo. This patch avoid to prefix them by sudo each time or call su.

If PKGDEST is set when makepkg was run, the package will be present in
find_cached_package's search path by default, causing an error.

This also fixes a display bug which causes no output to be shown when
multiple packages are found.

Fixes FS#37626.

This function (currently) searches through $PWD and $PKGDEST looking
for a tarball matching the requested package name, architecture, and
pkgver. If found, it writes the full path to the located package to
stdout and returns 0, else 1. If more than 1 match is found, it's
treated as an error and the user will need to figure out what to do.

Use this in checkpkg and commitpkg, which previously implemented their
own less complete logic, to locate the build artifacts they rely on.

Also allow this function to be called without arguments, in which case,
don't call error at all. Some uses of this function wrongly assumed
that this was already allowed.

Reduces code duplication.

With makechrootpkg not calling mkarchroot anymore,
the lock handover protocol is unneeded.

arch-nspawn does not do any locking, so add protection to archbuild.

Stop trap_exit from forcing a 0 exit code. This fixes makechrootpkg,
which used to always return success, even if the build failed.

* Honor TMPDIR variable (just like we did in commit a0c6bf45

).
* Quote path properly.
