[PATCH 0/2] package: replace copydebugsources shell pipelines with Popen

[Anders Heimer <anders.heimer@est.tech>]

Continue the OE-Core shell=True cleanup in oe.package.

Replace the copydebugsources() shell pipelines with explicit Popen
chains using argv lists, env= for LC_ALL and cwd= for cpio. Also replace
the externalsrc mv shell glob with glob.glob(glob.escape(...)) so
metacharacters in the directory path are handled literally.

The first copy pipeline keeps the previous failure-tolerant behavior,
while the symlink fixup pipeline now checks each stage directly. Add
oeqa tests for normal copying, symlink dereferencing, multiple
-ffile-prefix-map entries, ignored source paths, and externalsrc
relocation.
