Subject: [PATCH] serial_port_linux: Add missing include sys/time.h

POSIX says `struct timeval` is defined if <sys/time.h> is included.

Adding this header allow to build against musl-libc.

Signed-off-by: Romain Naour <romain.naour@smile.fr>
(cherry picked from v1.4 branch commit 661405eb6066b67dfe51d5ff9635e29f86bdd238)
