fstrim: initialize path variable

Reading the code this initialization is not necessary, so the change is
mostly about silencing a compiler warning and ensuring the program keeps
on working if there is a future bug that could make uninitialized 'path'
reachable to use.

sys-utils/fstrim.c:247: warning: 'path' may be used uninitialized in this
function
