Makefile: add SANITIZE=leak flag to GIT-BUILD-OPTIONS

avar · gitster · commit 2cdc292b3160 · 2021-09-23T11:29:45.000-07:00
When SANITIZE=leak is specified we'll now add a SANITIZE_LEAK flag to
GIT-BUILD-OPTIONS, this can then be picked up by the test-lib.sh,
which sets a SANITIZE_LEAK prerequisite.

We can then skip specific tests that are known to fail under
SANITIZE=leak, add one such annotation to t0004-unwritable.sh, which
now passes under SANITIZE=leak.
