package/google-breakpad: fix build on modern hosts

Since glibc 2.30, a tgkill() function is exposed by the C library, but
google-breakpad has its own internal definition of it, which now
conflicts. This causes build failures on modern build machines (when
building google-breakpad for the host).

This commit adds a patch that simply renames the internal tgkill()
function to BreakpadTgkill() to avoid the naming conflict.

We do that instead of a configure.ac change to avoid having to
autoreconf this package, and because the fix is anyway not
upstreamable as upstream simply dropped the internal tgkill()
implementation, but using that would break building google-breakpad on
older systems.
