bash: Update version to 5.2 with patches 1 to 15

Browse Source 
- Update from version 5.2 patches 1-9 to 5.2 patches 1-15
- Update of rootfile not required
- Changelog
bash52-015
	There are several cases where bash is too aggressive when optimizing out forks
	in subshells. For example, `eval' and traps should never be optimized.
bash52-014
	Bash defers processing additional terminating signals when running the
	EXIT trap while exiting due to a terminating signal. This patch allows the
	new terminating signal to kill the shell immediately.
bash52-013
	Bash can leak memory when referencing a non-existent associative array
	element.
bash52-012
	When running in bash compatibility mode, nested command substitutions can
	leave the `extglob' option enabled.
bash52-011
	Using timeouts and readline editing with the `read' builtin (read -e -t) can
	leave the readline timeout enabled, potentially resulting in an erroneous
	timeout on the next call.
bash52-010
	Bash-5.2 checks the first 128 characters of an executable file that execve()
	refuses to execute to see whether it's a binary file before trying to
	execute it as a shell script. This defeats some previously-supported use
	cases like "self-executing" jar files or "self-uncompressing" scripts.

BASH PATCH REPORT
=================
Bash-Release: 5.2
Patch-ID: bash52-015
Bug-Reported-by: Frode Nordahl <frode.nordahl@canonical.com>
Bug-Reference-ID: <20221119070714.351759-1-frode.nordahl@canonical.com>
Bug-Reference-URL: https://lists.gnu.org/archive/html/bug-bash/2022-11/msg00078.html
Bug-Description:
There are several cases where bash is too aggressive when optimizing out forks
in subshells. For example, `eval' and traps should never be optimized.
Patch (apply with `patch -p0'):
