uClibc declares posix_fadvise() even when the architecture does not provide
one. The static posix_fadvise() signature is not compatible with POSIX. Rename
the internal implementation to fix this. Fixes the following build failure
when building against uClibc:
e4defrag.c:189:2: warning: #warning Using locally defined posix_fadvise interface. [-Wcpp]
e4defrag.c:203:12: error: conflicting types for ‘posix_fadvise’
