BSD grep not detected properly :)

When using BSD grep no warning shows up reminding you to use the (right) GNU grep.

 /usr/bin/grep --version
grep (BSD grep, GNU compatible) 2.6.0-FreeBSD

Ahh yeah that's because of

scwrypts/zsh/lib/utils/dependencies.zsh

Line 40 in 6b15491

$UTIL --version 2>&1 | grep -q 'GNU' || {

Those tricksters have fooled me yet again!

"GNU compatible" lmao

BSD GREEEEEEPP!

Although not particularly elegant, there's not a really standard output from all the --version outputs of these utilities, so I've included a fix which detects this case in addition to the previous checks to help throw warnings on BSD utilties.

This is live as of the 4.1.3 release
