chore(gitignore): Re-order exclusion patterns.

My original PR #18207 attempted to address the
aggressiveness of our .gitignore matches for known binary names.

Unfortunately, new directories with these names are now being ignored
when they shouldn't (thanks @jsternberg). Upon further investigation, it
looks like the only problematic patterns in the original code were the
plain (non-globbed) patterns like `influxd` and `influxdb`.

Returning the globbed patterns to their original order fixes the problem
while still holding onto the characteristic of being able to see
directories like `cmd/influxd/launcher` via tools that use .gitignore
for exclusion patterns. Below is an overview of how I've verified the
changes.

Regular files matching know binary names should be ignored anywhere in
the tree:

    $ echo "hello" > influxd
    $ echo "hello" > dbrp/influxd
    $ git status
    ## bb/reorder-exclusion

Directories matching known binary names should not be ignored anywhere
in the tree:

    $ mkdir influxd
    $ echo "hello" > influxd/hello.txt
    $ mkdir dbrp/influxd
    $ echo "hello" > dbrp/influxd/hello.txt
    $ git status
    ## bb/reorder-exclusion
    ?? dbrp/influxd/
    ?? influxd/
    $ git status --untracked-files
    ## bb/reorder-exclusion
    ?? dbrp/influxd/hello.txt
    ?? influxd/hello.txt

New files in existing directories matching known binary names should not
be ignored:

    $ echo "hello" > cmd/influx/hello.txt
    $ git status
    ## bb/reorder-exclusion
    ?? cmd/influx/hello.txt

I've also made changes to already indexed files like
`cmd/influxd/launcher/engine.go` and those changes aren't ignored.
