[PATCH] busybox: tr: enable options required by POSIX

[Magnus Kroken]

Support for character classes (e.g. [:upper:] and [:lower:]) and
equivalence classes (e.g. [=a=]) in the tr utility are required by POSIX.
This change increases package size by approx. 500 bytes.

Size before:
208372 busybox_1.31.1-1_mips_24kc.ipk

Size after:
208895 busybox_1.31.1-1_mips_24kc.ipk

This was discussed a few days ago [1], but the patch wasn't caught by
Patchwork. Resending.

Jordan: I was not able to apply your patch, but it was easy enough to
fix. Please consider using git-send-email for future patches, as it
ensures it is formatted so Patchwork [2] will keep track of it, and
solves most formatting issues that may occur between author and committer.
