tag: fix out of bounds read when searching for tag message
When parsing tags, we skip all unknown fields that appear before the tag
message. This skipping is done by using a plain `strstr(buffer, "\n\n")`
to search for the two newlines that separate tag fields from tag
message. As it is not possible to supply a buffer length to `strstr`,
this call may skip over the buffer's end and thus result in an out of
bounds read. As `strstr` may return a pointer that is out of bounds, the
following computation of `buffer_end - buffer` will overflow and result
in an allocation of an invalid length.
Fix the issue by using `git__memmem` instead. Add a test that verifies
parsing the tag fails not due to the allocation failure but due to the
tag having no message.

tests: add tests that exercise tag parsing
While the tests in object::tag::read exercises reading and parsing valid
tags from the ODB, they barely try to verify that the parser fails in a
sane way when parsing invalid tags. Create a new test suite
object::tag::parse that directly exercise the parser by using
`git_object__from_raw` and add various tests for valid and invalid tags.
