brotli: update to version 1.0.7

The new version, among other changes, includes important fixes
for unaligned memory access on ARM (both for 32 and 64-bit), as well
as performance improvements and build fixes.

Patch "0001-Tell-CMake-to-not-check-for-a-C-compiler.patch" is not
needed due to the issue being fixed upstream, and therefore is removed.

Patch "0001-CMake-Allow-using-BUILD_SHARED_LIBS-to-choose-static.patch"
is rebased against the latest upstream changes.
