gcc-plugins/stackleak: Exactly match strings instead of prefixes
[ Upstream commit 27e9faf415dbf94af19b9c827842435edbc1fbbc ]
Since STRING_CST may not be NUL terminated, strncmp() was used for check
for equality. However, this may lead to mismatches for longer section
names where the start matches the tested-for string. Test for exact
equality by checking for the presences of NUL termination.
