beef up write syscall tests
Added a few tests for write(2) and pwrite(2)
1. Regular Files
For write(2)
- write zero bytes should not move the offset
- write non-zero bytes should increment the offset the exact amount
- write non-zero bytes after a lseek() should move the offset the exact amount after the seek
- write non-zero bytes with O_APPEND should move the offset the exact amount after original EOF
For pwrite(2), offset is not affected when
- pwrite zero bytes
- pwrite non-zero bytes
For EOF, added a test asserting the EOF (indicated by lseek(SEEK_END)) is updated properly after writing non-zero bytes
2. Symlink
Added one pwite64() call for symlink that is written as a counterpart of the existing test using pread64()
