dev-python/reportlab: revbump 3.6.11-r1, add sparc SIGBUS patch

This actually fixes a real bug that normally only would have manifested
under specific conditions (possibly crafted input file) but was revealed
due to sparc's alignment requirements.  Initially misidentified as a
cpython bug [1] but the cpython devs helpfully clarified and pointed in
the right direction [2].

+Subject: [PATCH] correct srclen type in gstate__aapixbuf
+
+gstate__aapixbuf calls PyArg_ParseTuple with the format string
+"ddddy#ii|i".  Specifically the key "y#" will try to read a bytes-like
+object and its size into two Python variables.  The latter of these
+should be of type Py_ssize_t as specified by the C API, but here it is
+incorrectly declared as an int.  This was pointed out to me by the
+cpython developers when I mistakenly identified it as a cpython bug and
+submitted a PR there:  https://github.com/python/cpython/issues/94149
