Hello Hung-Te Lin, build bot (Jenkins), Nico Huber, Subrata Banik,

flashrom.c: Implement file-based locking semantics
This upstreams the ChromiumOS implementation of file-based locking
for multiple instances of flashrom that could be spawned either
from libflashrom (perhaps by fwupd for example) and user cli
as another example. Since flashrom is programming singleton state
of hardware from userspace there is no way to exclusively own
the address space and therefore a file-based locking semantic
is considered here.
BUG=b:217629892,b:215255210
BRANCH=none
TEST=nm -gD /build/brya/usr/lib64/libflashrom.so | grep "flock"
Test futility update with multiple instances of flashrom running.

tests/: Allow realtek_mst test to check multiple paths
While working on writing file-based locking for flashrom
it was observed that the realtek_mst unit-test does not
check subsequent paths from the io_mock state tracker.
Add infrasture into the realtek_mst unit-test to allow
for subsequent path validation.
BUG=b:217629892,b:215255210
TEST=`ninja test`.
