GN: Fix some breakage for os==chromeos build

build/config/linux/BUILD.gn:
* Usage of generate_library_loader for libbrlapi was incorrect; there
* was nothing provided for "functions". This is now an empty list.

chrome/chrome_common.gypi
chrome/common/BUILD.gn
* Reference to a removed file, chrome_version_info_linux.cc

chromeos/BUILD.gn
components/pairing/BUILD.gn
* Usage of removed proto_{in,out}_dir in proto_library rules.

content/gpu/BUILD.gn
* Typo in reference to third_party/libva:libva_config

ui/views/BUILD.gn
* Attempt to filter source files out of
* gypi_values.views_unittests_sources by subdirectory path. Fortunately
* that variable already doesn't include the files that were supposed
* to be filtered out, so the rule is simply removed.

BUG=388412
TEST=Create a target that builds //mojo/public, build with os==chromeos
