Lancelot SIX 090b1804b7 bash_5: upgrade readline dependency to 8.1
Readline 8.1 is required for bash-5.1 to work properly.

From bash-5.1 release message[1]:

> Bash can be linked against an already-installed Readline library
> rather than the private version in lib/readline if desired.  Only
> readline-8.1 and later versions are able to provide all of the symbols
> that bash-5.1 requires; earlier versions of the Readline library will
> not work correctly.

longDescription = ''
Bash is the shell, or command language interpreter, that will
appear in the GNU operating system. Bash is an sh-compatible
shell that incorporates useful features from the Korn shell
(ksh) and C shell (csh). It is intended to conform to the IEEE
POSIX P1003.2/ISO 9945.2 Shell and Tools standard. It offers
functional improvements over sh for both programming and
interactive use. In addition, most sh scripts can be run by
Bash without modification.
