Add new codepage charmaps/IBM858 [BZ #21084]

This code page is identical to code page 850 except that X'D5'
has been changed from LI61 (dotless i) to SC20 (euro symbol).

The code points from /x01 to /x1f in the /localedata/charmaps/IBM858
file have the same mapping as those in localedata/charmaps/ANSI_X3.4-1968.
That means they disagree with with

ftp://ftp.software.ibm.com/software/globalization/gcoc/attachments/CP00858.txt

in that range.
For example, localedata/charmaps/IBM858 and localedata/charmaps/ANSI_X3.4-1968 have:

   “<U0001>     /x01         START OF HEADING (SOH)”

whereas CP00858.txt has:

   “01 SS000000        Smiling Face”

That means that CP00858.txt is not really ASCII-compatible and to make
it ASCII-compatible we deviate fro CP00858.txt in the code points from /x01
to /x1f.

	[BZ #21084]
	* benchtests/strcoll-inputs/filelist#en_US.UTF-8: Add IBM858 and ibm858.c.
