Replace lseek64 with lseek

meson defined _FILE_OFFSET_BITS=64 unconditionally, this implies that
lseek and lseek64 are both same since they are using 64bit off_t,
replacing lseek64 with lseek also helps in compiling with latest musl C
library which has removed these from _GNU_SOURCE namespace unlike glibc
where _GNU_SOURCE also implies _LARGEFILE64_SOURCE and the definition of
lseek64 is still available.
