ls: gnu test case color-ext compatibility

[matrixhead]

The GNU test case color-ext was failing because our ls command doesn't handle suffix letter cases.

example 1

touch img1.jpg IMG2.JPG img3.JpG file1.z file2.Z
LS_COLORS="*.jpg=01;35:*.JPG=01;35;46" ls -U1 --color=always   img1.jpg IMG2.JPG img3.JpG

our ls would produce output

^[0m^[01;35;46mimg1.jpg^[0m
^[01;35;46mIMG2.JPG^[0m
^[01;35;46mimg3.JpG^[0m

but it should be

^[0m^[01;35mimg1.jpg^[0m
^[01;35;46mIMG2.JPG^[0m
img3.JpG

like wise

example 2

LS_COLORS="*.jpg=01;35;46:*.jpg=01;35:*.JPG=01;35;46"   ls -U1 --color=always img1.jpg IMG2.JPG img3.JpG 

our ls would give

^[0m^[01;35;46mimg1.jpg^[0m
^[01;35;46mIMG2.JPG^[0m
^[01;35;46mimg3.JpG^[0m

but it should be

^[0m^[01;35mimg1.jpg^[0m
^[01;35;46mIMG2.JPG^[0m
img3.JpG

In both cases, this is happening because lscolors doesn't care about the case sensitivity of the entries in the env.

sorry, I was typing it and accidentally pressed Ctrl+enter

I already made an issue in lscolors's repo and working on a fix
