[PATCH v1] travis-ci: ask homebrew for the its path instead of hardcoding it

[larsxschneider@gmail.com]

From: Lars Schneider <larsxschneider@gmail.com>

The TravisCI macOS build is broken because homebrew (a macOS depedency
manager) changed its internal directory structure [1]. This is a problem
because we modify the Perforce dependencies in the homebrew repository
before installing them.

Fix it by asking homebrew for its path instead of hardcoding it.

Hi Junio,

the problem affects all branches (pu, next, master, maint):
https://travis-ci.org/git/git/branches

Is it possible for this fix to graduate more quickly?

Thanks,
Lars
