package/rockchip-mali: fix hash of generated archive

The "official" repository we used to reference disapeared quite some
time ago, so in commit 8c25838b53e6 (package/rockchip-mali: fix build
failure due to missing URL) we switched to using a mirror.

The tarballs generated on the Github side have a top-level directory
that is named "repo-name-HASH", so when we switched to a repository
named "libmali" to one named "mirrors", the content of the generated
tarball changed, even though the content of the files did not.

We can't just change the hash to the new value, or that would conflict
with the copy on s.b.o and older versions of Buildroot.

So, we drop one char from the commit hash, which eans the tarball name
changes, and thus we can calculate a new hash for that tarball, and
there will be no conflict with any existing tarball on s.b.o.
