package/exfat-utils: fix compilation error with musl

exfat-utils build would not build on Linux unless __GLIBC__ was defined. Patch added to use more relaxed __linux__ instead.

See http://autobuild.buildroot.net/results/c60/c60d0f9a93c90d41c3c86c78b0a0

Changes v1 -> v2 :
- removed unnecessary dependency change
- improvements (much simpler patch) as suggested by Thomas P

+[PATCH] fix compilation when libc does not define __GLIBC__
