torbrowser-launcher fixes (#6270)

Apparently Tor Browser 13.0.11 (based on Mozilla Firefox 115.8.0esr)
changed a few things. The former versions installed under
`${HOME}/.local/share/torbrowser/tbb/x86_64/tor-browser_en-US/Browser`
and now under
`${HOME}/.local/share/torbrowser/tbb/x86_64/tor-browser/Browser`.

All of our tor-browser-foo.profile profiles redirect to
torbrowser-launcher.profile and are covered by the fixes.

torbrowser.profile was not tested. It redirects to
firefox-common.profile and seems to be Gentoo-specific.

Fixes #6269.
