Changes

Build the binary used by test_redundant_seccomp_rules test in an alternative build directory.

Reason

test_redundant_seccomp_rules builds the Firecracker binary using the nightly toolchain (we need this to be able to run its static analysis). This replaces the binary used by all subsequent tests and it causes them to fail since nightly might introduce a system call that is not allowed by our seccomp rules.

@bchalios bchalios force-pushed the fix_redundant_seccomp_rules branch from 7f33aa8 to a34e765 Compare September 15, 2025 08:21
test_redundant_seccomp_rules builds the Firecracker binary using the
nightly toolchain (we need this to be able to run its static analysis).
This replaces the binary used by all subsequent tests and it causes them
to fail since nightly might introduce a system call that is not allowed
by our seccomp rules.

In order to avoid such situations, build the binary used by the test in
a different build directory.
