Fix libc++ dependency for linux installer

Without this dependency, "gn gen" complains that libc++ isn't generated by any dependencies of the targets when building an ASAN build with is_chrome_branded=true on Linux.

Here are the gn args I used:

is_chrome_branded = true
is_asan = true
is_component_build = false
is_debug = false
is_lsan = true
symbol_level = 1

Here are the errors:

Generating files...
ERROR Input to targets not generated by a dependency.
The file:
  //out/GN_Asan/lib/libc++.so
is listed as an input or source for the targets:
  //chrome/installer/linux:stable_deb
  //chrome/installer/linux:stable_rpm
  //chrome/installer/linux:beta_deb
  //chrome/installer/linux:beta_rpm
  //chrome/installer/linux:unstable_deb
  //chrome/installer/linux:unstable_rpm
  //chrome/installer/linux:trunk_deb
  //chrome/installer/linux:trunk_rpm
  //chrome/installer/linux:asan_deb
  //chrome/installer/linux:asan_rpm
but no targets in the build generate that file.
